Others are commonly referred to as Kalrez® -Rings (DuPont Dow), Chemraz® -Rings (Greene, Tweed & Co.), Isolast® -Rings (Trelleborg Sealing Solutions), and lesser quality brands such as Perlast (Precision Polymer Engineering), GPlast (Gapi) and Markez® (Marco). Since hydraulic seals are so critical to the efficiency of hydraulic systems, they are applicable across a wide range of industries. Piston Seals are radial seals. After the removal of all -rings, the parts that receive new -rings have to be cleaned and inspected to make sure that they are free from all contamination. Hydraulic seals of various makes sometimes have very long delivery times. Our offer includes high quality seals for hydraulic cylinders used in the industry and agriculture. When properly installed in a groove, an -ring is normally slightly deformed so that the naturally round cross-section is squeezed diametrically out of round prior to the application of pressure. For example, spherical bearing ran a series of brutal tests to determine how much fluid pressure a common nitrile -ring can withstand without extruding into the gap. KAF’s lip design was developed with integral preloading to be automatically self-sealing under high and low pressure. 4. Preventing blowouts: Blowouts on oil plants can be reduced to a great extent by using industrial seals. The main tasks of the seals are retaining lubricants, excluding contaminants adn maintaining the hydraulic pressure. X rings (also known as quad or square rings) are, in essence, enhanced versions of -rings. Wiper seals remove these contaminants when they retract into the cylinder. Our hydraulic seals are outfitted with seven precision-manufactured components. The UTS seal has small dimensions and has been created for cylinders under possible high pressure and speed variations. This allows pressure build up on one side of the piston, making the Cylinder extend or retract. Seal House offers a comprehensive range of Rod Seals in a variety of styles and materials to suit most applications. These seals protects the rod seals from the damages caused as a result of pressure rise. Based on criteria such as operating temperature, chemical interactions, pressure and fluid types, we select the materials that can handle each environment best. An elastomer which provides dynamic and static sealing against the shaft. A sealing lip has an edge which is formed by pressing, cutting or grinding and is normally pressed against the counterface on the shaft with a defined radial force by a spring. A high pressure hydraulic seal is usually surrounding rods, rams, glands or the piston and used a different design or combination of interlocking lips and components. The seals are located in the piston, on the cylinder head or on the rod shaft. The uses of rod seals vary from medium to high-duty applications with robust sealing effects. Types od seals include Vee-ring packings, urethane U-seals & polyurethane U-seals & double reversed packing sets. Fluid type, pressure, temperature requirements, speed of movement, environmental conditions chemical contact and many more factors are considered when choosing the most suited material. Hydraulic wear rings guide the piston and rod within the cylinder, absorbing forces and preventing metal-to-metal contact. Please see our products below and a Catalogue of hydraulic seals (PDF file, 11 MB). They are internal to the cylinder head and seal against the cylinder bore, preventing fluid flow. Skega’s success in this field has been built up around the well‐tried ‐ring seal which is combined with a new type of support ring and guide ring, produced in a new material and protected by the Swedish Patent No 221178. They have an enhanced extrusion resistance at high pressure and low temperatures and are used with heavy-duty cylinders. Dynamic (used when parts are in motion) or static (fixed application), different types of seals, each have their own role to play, in ensuring a cylinder runs as smoothly as possible. CDK Seals started out as a family-run business to supply PTFE seals, spring energised seals, rubber mouldings and hydraulic seals.

Hydraulic seals are crucial in machinery equipment. SSP Seals’ stocks a wide range of hydraulic and pneumatic seals to meet the various needs of industrial applications in terms of design, manufacturing, and application performance. These seals create a tight fit by allowing the passage of reciprocating ramrod through the inner bore of the seal. Bill of Material – A list of all materials needed to manufacture a certain product. For use as an anti-extrusion device in dynamic -ring applications where there is high pressure or excessive gland clearance. Typically called out as “cast” urethane -rings, these parts perform well in quick disconnects, high pressure hydraulic and water applications and in nail or riveting equipment. Wipers work in conjunction with rod seals to protect a system and keeping it free from dirt, mud, water, and other contaminants. This seal design is offered as a rod or piston seal and provides outstanding performance in both hydraulic and pneumatic applications. Snap-in wiper designed to scrape outside contaminants off cylinder rods in medium to heavy-duty hydraulic cylinders. Chesterton” 9K anti-extrusion rings, often referred to as back-up rings, are designed to prevent seals or -rings from extruding into equipment clearances while under pres- sure. To do so would require a combination highly precise machining, unusual materials, low stress on components, and specific fluids—and even then, such a system would fail relatively quickly. Dynamic Seals – Dynamic seals are used when axial or radial movement is required under pressure. These -rings are now standard for systems where the operating temperatures may vary from -65 °F to +275 °F. Contact GBSA today to discuss hydraulic wipers specific to your application. Loaded Lip Seals are very versatile and can be used as rod seals or piston seals. We enjoy the challenge of providing solutions to the most difficult seal applications. Than the inner lip in order to be used for piston applications. KAF’s unique polymer material features high wear resistance and elasticity, thus preventing the damage that commonly occurs during installation. In hydraulic applications, each of the pneumatic seals plays a critical role in keeping the system running efficiently. Lip Seals are for use in rotary applications up to 150 psi in corrosive and abrasive environments. Adjustable packing used in telescoping cylinders and many types of older hydraulic equipment. Within the aerospace industry, custom seals such as silicone sealant strips serve to seal various hydraulic components within aircraft systems. Back-up rings are not seals themselves. Double-acting piston seals are able to concentrate pressure on both sides of a piston, thus driving the ram that the piston is typically attached to. In contrast to the dynamic types of piston seals just described, static piston seals seal the gap between the piston and the piston rod (rather than the piston and the cylinder bore). The hydraulic environment is very extremely tough on seals which must withstand enormous amounts of pressure as well as extreme temperatures and often unbalanced forces and extreme forces inside a cylinder. Various types of seals are used in applications that have constantly moving equipment, such as the rotating or reciprocating shafts and cylinders that are an essential part of hydraulic and pneumatic systems. One basic hydraulic cylinder system may make use of hydraulic cylinder seals , lip seals , hydraulic piston seals, wear rings, scrapers, and more to function effectively. If you have plans for upgrades or expansion of operations in the future, this may impact the best solution for hydraulic seals today. Parker offers a complete range of both activated and non-activated PTFE piston seals and rings for hydraulic and pneumatic applications. Piston seals may also be known as Piston Packing. ISO 9001:2015 manufacturer & designer of mechanical seals, hydraulic seals & pneumatic seals. The seal is designed with initial radial interference to effect low pressure sealing. Piston seals are used to prevent pressurized fluid from leaking across the cylinder head while system pressure pushes the piston down the cylinder bore.

This reduction in squeeze means less friction and improved seal life, and because parting lines are between the lobes, away from the sealing surface, problems of leakage associated with -rings is virtually eliminated. WRB Wiper Seals: These Medium Duty scraper seals have a special lip that help prevent moisture and dirt from accumulating on the rod. If the clearance gap between the sealing surface and the groove corners is too large or if the pressure exceeds the deformation limits of the -ring material (compound) , the -ring will extrude into the clearance gap, reducing the effective life of the seal. Manufacturer of standard and custom hydraulic seals. GUARNITEC use very high quality polyurethane compounds and other materials in their production. Many hydraulic seal suppliers have the same exact seals that are used in most hydraulic cylinders and can easily cross reference or match up a replacement. When the wiper seals are not secured or fail, it can cause component failure in a fluid power system that leaves other pieces of the operation open to serious damage. For heavy-duty hydraulic cylinders. You’ve discovered -Rings, Inc. Despite the greatest of care, conventional seals are highly vulnerable to damage of the sensitive sealing faces during installation. 3. Leakage control: The use of hydraulic seals can prevent any leakage, thus reducing any chances of downtime or repair. The specific operations of a hydraulic seal differ slightly depending on where the seal is located with regard to the hydraulic cylinder. Hydraulic seals should be a fairly high priority for checkups by your maintenance team. T-seals are composed of a sealing element with two split back-up rings. Industries hydraulic seals serve include aerospace manufacturing, agriculture, automotive manufacturing, chemical processing, defense contracting, food processing, marine products manufacturing, medical and pharmaceutical products development, nuclear power, pulp and paper, and waste disposal. Rods seals, piston seals, wipers, guiding rings and statics seals on stock. Rod Seals: These hydraulic seals are used to prevent fluid leakage within cylinder. Static seals that installed directly into the housing or glands of a system, rod seals are designed to provide dynamic sealing pressure while the piston rod is in dynamic motion. The external lip scrapes foreign matter from the rod, and the other lips act as an effective pressure seal in low pressure applications. Furthermore, purchasers of hydraulic seals should take note of vacuum rating, working temperatures, chemical compatibility (between the seal and the hydraulic fluid), highest and lowest working speed, and minimum and maximum pressure. Because System Seals specializes in custom designs and sizes, the company is a perfect fit for the cylinder repair industry, and it continues to save its customers millions of dollars each year. Asymmetrical seals are so designed that in the installed state they contact the static surface with an initial stress over the whole axial width in order to achieve a sufficiently firm seating in the groove. Wipers are designed to prevent any contamination to the system by external media during stroke movement of the cylinder. We will work with you to ensure our rod seal designs meet your application requirements. U-ring packings (AN6226) and U-cup packings are used in brake assemblies and brake master cylinders. FKM – When applications that require better chemical resistance and higher temperatures up to 400°F (FKM seal elements) with two PTFE or PEEK back-ups are recommended. Hydraulic rod seals are installed in a groove that has been machined in the cylinder housing to provide a tight seal against the piston shaft. These anti-extrusion rings are available in various extrusion-resistant materials and are located on the back-side or low pressure side of the sealing element they are supporting. Sealing Devices has experience with custom aerospace seals, and offers many items including geltek silicone sealant strips from stock. In addition to keeping fluid from leaking, seals also help keep dirt and contaminants out of the cylinder, which extends the lifespan of the cylinder.

The first name in -Rings since 1958 with the right attitude, the best service, and value. The immense clearance in between the machine’s piston and cylinder wall can be isolated and cover up with this seals. An important characteristic of -rings is the compression set, or measure signifying how much an elastomer regains its initial thickness after being compressed. We offer a wide range of hydraulic seals suitable for different cylinder types and industries. Figure 1 Hydraulic seals used between nonmoving fittings and bosses are normally called gaskets. They have a quad-ring loader that makes the seal a good choice for low-pressure rod applications. Of course, not every machine contains both rods and pistons, so be sure you know the difference between the two, and which one is the type of seal that you need. Cylinder repair shops can easily upgrade stock OEM seals with highly engineered System Seals products for greater reliability and performance. Some of the rubber materials used to create seals are nitrile, silicone, natural rubber, butyl and styrene butadiene. We are offering our client an excellent quality range of Hydraulic Seal. Seals prevent or reduce fluid passage between 2 surfaces. The most common profiles and designs per seal type and guides are: piston seals, rod and buffer seals, wiper seals, guide rings and guide strips, -rings and back-up rings. Rod seals and piston seals prevent leakage of fluid from cylinders and stop pressure buildup. Heavy-duty rod seals for mobile and heavy duty industrial equipment. Hydraulic Seals are generally made out of a variety of materials, including Rubber, PTFE , and Polyurethane (AU) Compatibility of the materials is decided upon the particular operating medium or restraints due to pressure, fluid type, temperature or chemical compatibility. Primary rod seal when used in sealing system in combination with BT U-cup. Rod Seals, which guard against external leakage, are one of the most vital components of the sealing system. Aircraft hydraulic components and systems require custom seal engineering to achieve minimal leakage and maximum performance to insure long seal life, and optimize safety concerns. Depending on the application and the type of seal you’re using, preventative maintenance measures may be one the most critical aspects of maintaining optimized performance. Usually made of some type of soft, flexible elastomer that provides exceptional water and air sealing capabilities, hydraulic seals are ring-shaped and primarily designed to eliminate or limit the leakage of fluid moving within a hydraulic or pneumatic system. Ic seals, polypack seals, wiper seals, guide ring, -ring seals, Teflon piston seals. Used as static, dynamic, radial or face seals. Back-up Rings are used in conjunction with -Rings for both static and dynamic sealing applications. Typical seal element materials are: Nitrile and FKM. As the rod rotates back and forth, they avert the leakage of the liquid from inside of a hydraulic cylinder to the outside (dynamic stress sealing). Our rod wipers are easy to install by simply snapping or pressing in, and come in a wide range of materials and styles. Our Hydraulic Seals products range includes -Rings and a number of innovative Seals designed for applications in hydraulic cylinders, such as the spring-energized Turcon® Variseal®, -Ring engergized Turcon® Stepseal®2K, Zurcon® polyurethane U-Cup RU9 and many more. For production workflows to run without a hitch it is vital for the power-transmitting, hydraulic fluid to remain enclosed within the system. Although hydraulic seals are primarily designed to prevent fluid leakage, it must be remembered that hydraulic seals provide other important functions and can only be properly maintained under the right conditions. We also design many seals with secondary lips to capture remnants that may have escaped the sealing. X rings can be used both as static seals and as dynamic seals. Custom manufacturer of seals for hydraulic industry. Just as rod seals are designed to keep fluid in, wipers keep contamination out. Back-up Rings: These seals are designed to solve the problem of seal extrusion.

High pressure, medium used, extreme temperatures, aggressive chemicals, working environment and legislation standards will all have an impact on the chosen material of seal. A hydraulic sealing product is actually a family of products used to seal reciprocating, oscillating or slow rotational movements caused by hydraulic equipment. As system pressure increases, the -ring is energized and forces the lips outward, changing its behavior from a squeeze type seal, to a traditional leap seal. Imperfect mating parts require some type of sealing device to be inserted between them to seal against loss of liquid, gas or solid fluids or particles. Chesterton’s broad range of high-performance hydraulic seals are made from exclusive polymer materials for use in a wide range of demanding industrial sealing applications. Over four million seals in a variety of case and lip styles. PTFE is the chemically inert of the -ring materials. Wear Rings are guiding elements that snap onto a shaft, both piston and rod, to keep metal from contacting metal that will damage and score the surface of a cylinder. Rod Seals are radial internal seals. Techné presents a compact range of hydraulic seals to fit your requirements : rod, piston seals, wipers, guiding rings and static seals on stock. V-Seals and V-Rings offer all rubber, one-piece construction of resilient seals to protect rotary shafts from dirt water and contaminants and extending bearing and shaft performance. For designs of medium to high pressure, it is recommended that fabric reinforced -rings be utilized. Piston seals are used in both pneumatic and hydraulic seals. The wiper seal needs to fit both the rod (dynamic) and also to the housing (static). Piston seals specifically work by preventing leakage or fluid flow across the piston. HydraPak stocks a substantial selection of hydraulic and pneumatic seals. Daemar’s line up of hydraulic seal products has been developed to provide exceptional value by combining the quality and performance that design engineers require with the total cost of ownership savings that today’s businesses demand. Wear rings or guide bands serve no sealing function. Shaft seals are tools that help to prevent the contamination of hydraulic shafts. 10. Wear-resistant: Typical hydraulic seals are wear-resistant and thus can be used in mining and extraction of minerals. When pressure is applied, it tends to force the -ring across the groove, causing the ring to further deform and flow up to the fluid passage and seal it against leakage. The U-ring and U-cup seals pressure in only one direction; therefore, the lip of the packings must face toward the pressure. These Parker seals and Parker -rings are offered in a variety of materials and lip geometries for the best possible solution for a given application. Hydraulic Rod seals prevent leakage of fluid from within the cylinder to the outside while hydraulic piston seals prevent fluid from flowing across the cylinder head. Misapplication or use of non-compatible materials can lead to chemical attack by fluid additives, hydrolysis and oxidation reduction of seal elements. They prevent the leakage of fluid from within a hydraulic cylinder to the outside as the rod cycles back and forth (dynamic pressure sealing). Piston Seals or Piston Rings are used in hydraulic cylinders for fluid sealing. Whether you’re looking for standard sizes or need a full set of custom hydraulic seals, we have the ability to provide any shaft seal type with our cutting-edge machining services. WDA Wiper Seals: These double-function seals use the lip to prevent contaminants from building up, yet also have an additional element that prevents scoring on a seal.
