Series 442

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 safetylocking feature prevents unintentional disconnection.
