threaded fitting / straight / test

The type SKK20 manufactured by STAUFF are test couplings with piston valves that are equipped with connection threads measuring M16 x 2. They are used in various operations such as hydraulic applications with low-viscosity fluids, pneumatics applications, natural gas applications with DVGW requirement SKK-DVGW, operations with high pulsating pressure. Fabricated from either steel, zinc or stainless steel, these test couplings generate a maximum working pressure capacity of 630 bar and a joining under pressure of 400 bar.

The SKK20 comes in three versions. The test coupling equipped with a port connection, a test coupling possessing a straight fitting and a test coupling that is designed for 24? cone fittings.
