Claw Couplings  

Claw Couplings are a symetric quick coupling system with two claws each, which are connected by simultaneously applying force and rotating the two claws to be 45° apart.

All connections and sealing systems have the same head dimensions; therefore all types are always interchangeable.

The recommended combination is a standard coupling with a MODY-coupling as the counter part (easy to couple, 100 % tight, absolutely safe).

It is very important to use always couplings made of malleable iron, which is as a result of its special heat treatment suitable for thin-walled parts and which is the only recommended casting material according to DIN 3489 and 3238
