Series 342, DN 7.4
- Automatic safety-locking feature
- Extremely high flow capacity
- One-hand operated
Series 342 couplings withstand extremely rough handling in extra tough applications. The Series features a zinc-plated steel 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.
