Item group
Safety compressor couplings with hose screw connection (DIN 3238), 42 mm
Exemplary representation: Safety compressor coupling with grommet, 16 bar malleable cast iron, galvanised, NBR seal
Exemplary representation: Safety compressor coupling with grommet, 16 bar 1.4401, NBR seal
detailed view: Compressor coupling dimensions
Application examples: Safety compressor coupling, turned back seal - easy coupling possible
Application examples: Safety compressor coupling, pre-screwed seal - connection is tight
Exemplary representation: Safety compressor coupling with grommet, 16 bar malleable cast iron, galvanised, NBR seal
Temperature range:
Steel or malleable cast iron: -40°C to +95°C, stainless steel: -30°C to +200°C
Note:
Brass seals are preferably used right at the compressor to prevent sticking of the seals from high temperature. The seal is held reliably in the coupling through free blow-off through the screw. Always use a coupling with a rubber seal as the counter-coupling.
All data are to be understood as non-binding reference values! We do not assume liability for any data selection not confirmed in writing. Unless otherwise specified, pressure values refer to liquids from Group II at +20°C.
