Air coupling (coupler) with residual pressure removal function eSafe 315
CEJN eSafe Coupling 315
One-touch connection with high flow rate. Excellent strength and durability!
The eSafe Series 315 offers excellent strength and durability while being lightweight and allowing for one-touch connection. Thread sealant is pre-applied to the male threads of the coupling and nipple. It employs a two-step method for separation, where you simply pull the sleeve and push to remove residual pressure before separating the nipple, preventing sudden disconnection and prioritizing the safety of the operator. It complies with international safety standards such as ISO 4414 and EN 983. Standard, soft line, and multi-link types are also available. For more details, please contact us or refer to the catalog.
