Cejn 10 550 2455 Safety Coupler 1/2 Inch Npt

Product Description

The CEJN 10 550 2455 is a male NPT safety coupler designed for pneumatic systems requiring reliable, quick-connect air line connections. Built with a brass and steel construction and a zinc-plated finish, this coupler is rated for a maximum working pressure of 232 psi and a temperature range of -4 degrees F to 212 degrees F. The 1/2-inch body diameter and 1/2-inch MNPT thread make it a direct-fit component for industrial-interchange pneumatic circuits. Licensed HVAC technicians, pipefitters, and maintenance professionals working on compressed-air systems are the primary installers.

This safety coupler is suited for industrial and commercial compressed-air distribution lines where the industrial-interchange standard is in use. The 1/2-inch hose inside diameter rating accommodates common mid-range air tool and equipment connections. Its safety-coupler design provides controlled air release on disconnect, reducing the risk of hose whip and unintended pressure surges. It is appropriate for shop air systems, pneumatic tool stations, and similar compressed-air applications operating within its rated pressure and temperature limits.

Key Features

• Safety coupler design provides controlled pressure release on disconnect
• Industrial-interchange coupling type for broad tool and fitting compatibility
• Maximum working pressure of 232 psi for demanding compressed-air applications
• Operating temperature range of -4 degrees F to 212 degrees F
• Brass and steel construction with zinc-plated finish for corrosion resistance
• 1/2-inch MNPT threaded connection for standard pipe and hose fitting integration

Compatibility

Designed as an OEM-style replacement or addition for pneumatic systems using industrial-interchange standard couplers with 1/2-inch NPT threaded connections.

Installation Notes

Installation should be performed by a qualified technician familiar with compressed-air systems. Depressurize and isolate the air line completely before removing or installing any coupler. Apply thread sealant appropriate for pneumatic service on the MNPT threads per the fitting manufacturer and applicable codes. Do not exceed the rated working pressure of 232 psi during operation.
