Series 315 eSafe, DN 7.5

  • Vented safety function
  • Extremely high flow capacity
  • Strong and durable


eSafe Series 315 couplings are lightweight and easy to handle yet strong and durable. It is a one hand operated safety coupling that vents before disconnection eliminating the risk of hose whip. The Series includes a wide range of connections. Male threads on the couplings and nipples feature pre-applied thread sealant. Full automatic operation ensures easy handling. eSafe complies with ISO Standard 4414 and EN 983.


Series 315 is also available in standard, Soft-Line and Multi-Link versions.
