Asian-profile couplings

Series 539

The Asian-profile couplings are designed to be as user-friendly as possible. They have an easy connection and disconnection that can be done with one hand. Furthermore, they are produced with an optimized valve system that reduces the connection force by 50% compared to the conventional valve systems currently available in the market.
JWL offers anti-whip nipples as accessories to our couplings.

The compatibility of the Asian-profile couplings is:
Standard: Nitto-Kohki 200
Flow diameter: 7,8 mm
Connectable with the following:
Nitto-Kohki 200, Cejn 314, Rectus 13 and many more

The JWL couplings and nipples with external thread can also be delivered with teflon.
