US-MIL quick couplings

JWL advantages:
Robust and impact-resistant quick couplings. All quick couplings are pressed together to prevent leaks. Low pressure drop thanks to optimised valve system. One-handed connection and release. Anti-whip nipples are available as accessories. The 521- & 531-Series are also available in stainless and acid proof steel.

Low connection force:
The series 511 and 571 are supplied with a user-friendly, new valve system that reduces the connection force by 50% compared to conventional valve systems currently available.

Safety coupling:
The 571 series has a two-step release system.

Heavy Duty:
The series 521 and 531 are suitable for heavy-duty use.


Vacuum quick coupling:
The seals/washers of the 511 series also make it suitable as a vacuum quick coupling.

Compatibility:
Standard : US-MIL-C 4109, 1/4”, ISO-6150 B, 1/4”
Flow diameter : 5,5 mm
Connectable with the following:
Atlas Copco Q8, Cejn 310, Hansen 1000, Rectus-Tema 23,24, and many more
