With the symmetric Guillemin couplings, connection is achieved through intermeshing of 4 upright claws. In mobile systems, generally, a coupling that is equipped with an adjustable clamping ring (locking) is used, which locks the claws upon twisting. In order for the connection to be set up, at least one of the coupling halves must be equipped with a lock. Only the coupling with locking is equipped with a soft seal.

Tankers, silos, industry and agriculture (mostly in France and BeNeLux)
