Pneumatic Products, eSafe Couplings & Nipples

Series 320 eSafe, DN 7.6

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

eSafe Series 320 coupling is an easy-to-handle high performing coupling with a long service life. eSafe is a one hand operated safety coupling that vents before disconnection eliminating the risk of hose whip. Male threads on the couplings and nipples feature pre-applied thread sealant. The couplings have a smaller outside dimension than comparable designs. Full automatic operation ensures easy handling. eSafe complies with ISO Standard 4414 and EN 983.


Serie 320 is also available in standard, Soft-Line and Multi-Link versions.
