Technical Description
The 65-67 series are quick connect couplings designed for use as pressure regulators for fuel, gas and oxygen as well as welding torches.

Advantages
Our „RectuKey“ coding system prevents mixing up media. Up to three different media can be safely (non-interchangeable) connected with the standard version. The 65 - 67 series can be equipped with both a safety locking system (ensures that an unintentional disconnection cannot occur) as well as without a safety locking system.

Working Pressure
PB = 35 bar, maximum static
working pressure with safety
factor of 4 to 1.
