Pneumatic Products, eSafe Couplings & Nipples

Series 381 eSafe, DN 8

  • Vented safety function
  • High flow capacity
  • Strong and durable


Series 381 eSafe couplings offer high flow and require only a low connection force, which ensures a safe working environment. eSafe is a one hand operated safety coupling that vents before disconnection eliminating the risk of hose whip. A fully automatic operation ensures quick and easy handling. eSafe complies with ISO Standard 4414.
