Cejn 10 310 2452 Safety Coupler 1/4 Inch Mnpt

Product Description

The CEJN 10 310 2452 is a Series 310 industrial safety coupler designed for pneumatic hose and tool connections in compressed-air systems. Built with a brass and steel construction and a zinc finish, it features a 1/4 inch male NPT threaded connection and a 1/4 inch body diameter. The coupler is rated to 230 psi maximum working pressure and handles temperatures from -4 degrees F to 212 degrees F, making it a reliable component for shop air, production lines, and service applications. Installation and disconnection require intentional two-stage engagement, which is the defining characteristic of a safety-style coupler.

This coupler suits light-duty to medium-duty industrial pneumatic systems where tool changes are frequent and accidental line disconnection poses a hazard. The industrial interchange profile makes it compatible with the broad range of fittings and tools built to that standard. Typical install locations include manufacturing floor drops, compressor outlets, and portable air tool stations. The threaded NPT connection allows direct installation into manifolds, regulators, or hose assemblies without additional adapters.

Key Features

• Safety coupler design requires deliberate two-stage release to prevent accidental disconnection
• Industrial interchange profile works with the widely used industrial fitting standard
• 1/4 inch MNPT threaded connection for direct installation into NPT-tapped ports
• 230 psi maximum working pressure rated for typical shop and production air systems
• Brass and steel construction with zinc finish for corrosion resistance
• Operating range of -4 degrees F to 212 degrees F covers most indoor and light outdoor service environments

Compatibility

Designed for use with industrial interchange pneumatic fittings and tools accepting a 1/4 inch body coupler with MNPT threaded connection.

Installation Notes

A licensed or qualified technician should depressurize the air line completely before removing or installing any pneumatic coupling. Use thread sealant tape or paste rated for compressed air on the NPT threads and tighten to a firm, leak-free connection without over-torquing the brass body. Verify that the connected system does not exceed the 230 psi working pressure rating of this coupler. Inspect the coupler and sleeve for wear or damage at each service interval.
