Guillemin coupling
Guillemin couplings are symmetrical quick couplings designed in accordance with EN 14420-8 / NF E 29-572.
Assembly
- Worm drive clamps
- Band clamps
- Aluminum double-jaw clamp
- Swage ferrules for helical hose shank
- Butt welding

Operation
The Guillemin coupling consists of a seal * on the mating surface and is closed by simultaneously inserting two identical coupling parts. This symmetrical coupling is closed by turning the locking ring a quarter turn and is sealed by tightening the locking ring behind the lugs. Additional closure is possible by locking the Guillemin coupling using the Guillemin GY wrench.
The locking rings of the Guillemin coupling can be rotated 360 ° is off.
* Seal only available for Guillemin couplings with locking ring
