Pneumatic Products, Safety Lock Couplings & Nipples

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.
