Type galvanised steel: Body, chain and cap: Galvanised steel, gaskets: NBR
Type 1.4571: Body: 1.4571, chain and cap: V2A, Seals: FKM
Temperature range:
-20°C to max. +100°C (1.4571: -20°C up to max. +200°C)
Application:
Test couplings are used to control the operating pressure as well as for venting if inconveniently laid tubes are in use. The screw coupling is closed and opens mechanically only after a measuring hose is screwed into it. In this way a connection is made to the medium.
