Cejn 10 315 2455 Safety Coupler High Flow Mnpt

Product Description

The CEJN 10 315 2455 is a safety coupler designed for pneumatic systems requiring high-flow air delivery with a secure, positive-locking connection. Built on CEJN's Series 315 platform, it features a 1/4 inch body diameter and a 1/2 inch male NPT (MNPT) threaded inlet. The body is constructed from brass and steel with a zinc finish, rated for a maximum working pressure of 230 psi. The operating temperature range runs from -4 degrees F to 212 degrees F, making it suitable for year-round shop and industrial service. Licensed HVAC technicians, plumbers, pipefitters, and industrial mechanics install this coupler as part of compressed air distribution lines and tool connection points.

This coupler is used in compressed air systems where high-flow interchange compatibility is required. Typical applications include production floors, vehicle service bays, construction jobsites, and mechanical rooms. The 1/2 inch hose inside diameter supports high-volume airflow for impact tools, pneumatic actuators, and similar demand loads. The threaded NPT connection integrates into standard pipe and fitting assemblies without adapters. It is suited for both permanent and service-loop installations where frequent tool changes occur.

Key Features

• High Flow interchange design supports maximum air delivery to demanding pneumatic tools
• Safety coupler style requires deliberate sleeve actuation to connect and disconnect, reducing accidental release
• 1/2 inch MNPT threaded connection for standard NPT pipe and fitting compatibility
• Brass and steel construction with zinc finish for corrosion resistance in shop environments
• Rated to 230 psi maximum working pressure
• Wide service temperature range: -4 degrees F to 212 degrees F

Compatibility

Designed as a High Flow interchange safety coupler compatible with Series 315 pneumatic coupler and plug systems using 1/2 inch MNPT threaded connections and 1/4 inch body diameter fittings.

Installation Notes

Installation is performed by a qualified mechanic or pipefitter. Depressurize and lock out the compressed air supply line before installing or removing any coupler. Apply thread sealant tape or compound to the MNPT threads per local piping codes before tightening. Do not exceed the rated working pressure of 230 psi for the system or connected tooling.
