by the arrangement of gaskets or rubber seals on both sides, otherwise glue is provided. Slip coupling is easier to install and it contains two pipes which are arranged as one into other, inner pipe can slide up to some length.

Buy cut lengths of welded & seamless stainless steel pipe online in Sch 10, Sch 40, Sch 80, and Sch 160. Crimped or pressed connections use special fittings which are permanently attached to tubing with a powered crimper. The fittings, manufactured with a pre-installed sealant or O-ring, slide over the tubing to be connected. High pressure is used to deform the fitting and compress the sealant against the inner tubing, creating a leakproof seal. Flange connections tend to be expensive, because of their requirement for precision forming of metal. To make a solder connection, a chemical flux is applied to the inner sleeve of a joint and the pipe is inserted.
The cones of the assembly studs are subject to normal wear and must be checked at regular intervals with taper gauges. Each screw sleeve must be used only once for finishing assembly on the pipe; using the same sleeve again may impair its function. This instruction describes the pre-assembly of a cutting ring on the pipe in a pipe screw sleeve or assembly stud. The surfaces of steel fitting bodies, union nuts and cutting rings are protected from corrosion as standard with a CrVI-free zinc-nickel coating conforming to DIN EN 15205.

Lightly oil the cone of the screw sleeve and the thread of the union nut. With sealing cone screw-on fittings with O-ring (AOL / AOS), the pre-stressing of the O-ring must be bridged and the sealing cone must lie metallically flush against the cone of the HL/HS connector. At this point, the cutting ring may be allowed to rotate, but must not move axially. Tightening torques for stainless steel fittings and for fittings with UN/UNF threads available upon request. The entire fitting consists of the threaded connector, the spacer ring with O-ring seal, the pressure ring and the union nut.
