Design: Push-button version. The shell is made of aluminium with oil- and heat-resistant NBR seals, button and valve are made from galvanised hardened steel the inner parts are made of stainless steel, and the thread is made of nickel-plated brass. The flow rate at 6 bar is 1600 l/min (air) (deltap=1 bar). These couplings conform to ISO Standard 4414.
