10 bar / 145 psi
Operation
The two couplings are pressed and twisted to seal. The teeth of the Express coupling are spaced at a standard 41 mm and are not interchangeable with the GK and European air couplings.
FEATURES
- Claw distance: 42mm
- Comes standard with a profile NBR seal giving excellent sealing properties and with an operating temperature range from -30°C / -22°F to 120°C / 248°F
- Machine-fitted seal
- Serrated hose end for perfect resistance when assembled with worm drive clamps or tooth clamps
- The high mechanical strength of the teeth of the Express coupling guarantees a longer service life
