Pneumatic Products, eSafe Couplings & Nipples

Series 416 eSafe, DN 10.4 Stainless Steel

  • Vented safety function
  • Extremely high flow capacity
  • Durable and robust for tough environments


CEJN eSafe Series 416 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 416 a perfect fit in aggressive environments, from cleaning solvents in food processing to the offshore industry.


Series 416 is also available in steel version, series 410.
