Safety Lock Couplings & Nipples

Series 442, DN 10.4

Automatic safety-locking feature
Extremely high flow capacity
One-hand operation

Series 442 couplings withstand extremely rough handling in extra tough applications. The series features a zinc-plated steel/brass construction with a locking sleeve made of hardened zinc-plated steel. The Series offers a wide range of connections, as well as anti-hose whip nipples. The automatic safety-locking feature prevents unintentional disconnection.

Please refer to the CEJN Breathing Air range for an all-brass version (Series 441).
