guillemin symmetrical couplings

Guillemin Symmetrical Thread Couplings

"Demi-raccord symétrique (Système Guillemin)" is a French-origin type of coupling for quick disconnection in the transfer of fluids at a pressuring rate PN 6~16.

They are symmetrical claw fittings. Two mating parts are closed with soft sealing (rubber-on-rubber and metal-on-rubber) by making the latch (locking ring) a quarter turn that sends the chamfered lugs into the claws.
