Pneumatic Products, eSafe Couplings & Nipples

Series 326 eSafe, DN 7.6 Stainless steel

  • Vented safety function
  • High-flow capacity quick disconnect
  • Durable and robust for tough environments


CEJN eSafe Series 326 is suitable for applications that require an easy to grip and high performing coupling. The eSafe series has a unique built-in safety function to avoid pneumatic recoil, and compared to other safety couplings, the eSafe series maintains a high flow. To provide the longest possible service life and thus save both the environment and money, all exposed components are made of stainless steel. This makes series 326 a perfect fit in aggressive environments, from cleaning solvents in food processing to the offshore industry. The eSafe connector complies with ISO Standard 4414 and EN 983.


Series 326 is also available in steel version, series 320.
