Cejn 10 320 2405 Pneumatic Safety Coupler 1/4 in

Product Description

The CEJN 10 320 2405 is a pneumatic safety coupler designed for compressed air systems requiring reliable, high-flow connections. Part of the CEJN Series 320, it features a 1/4-inch body diameter and a 1/2-inch female NPT (FNPT) threaded connection. The coupler is constructed from brass and steel with a zinc finish, built to handle working pressures up to 230 psi and temperatures ranging from -4 degrees F to 212 degrees F. This part is installed by mechanical contractors, industrial maintenance technicians, and pneumatic system specialists in both shop and field environments.

This safety coupler is suited for industrial and commercial pneumatic applications where high-flow interchange performance is required. The 1/2-inch hose inside diameter accommodates moderate to high air volume demands. The FNPT threaded connection allows direct installation into standard pipe fittings and manifolds. Typical use cases include air compressor outlet lines, pneumatic tool drops, and production floor air distribution systems where controlled release and safety coupling behavior are priorities.

Key Features

• High Flow interchange type for increased air delivery capacity
• 230 psi maximum working pressure rating
• Operating temperature range: -4 degrees F to 212 degrees F
• 1/2-inch FNPT threaded connection for standard pipe compatibility
• Brass and steel construction with zinc finish for durability and corrosion resistance
• Series 320 safety coupler design for controlled disconnection

Compatibility

Designed as an OEM-style replacement or direct-fit safety coupler for pneumatic systems using High Flow interchange-style couplings with 1/2-inch FNPT threaded inlets and 1/4-inch body diameter components.

Installation Notes

Installation is performed by qualified pneumatic or mechanical technicians. Always depressurize the air line fully before connecting or disconnecting couplers. Use appropriate thread sealant on FNPT connections per shop practice and applicable codes. Do not exceed the 230 psi maximum working pressure rating or operate outside the rated temperature range.
