Cejn 10 430 2405 Safety Coupler 3/8 in Fnpt

Product Description

The CEJN 10 430 2405 is a safety-style pneumatic hose coupler designed for industrial compressed-air systems. With a 3/8-inch body diameter and a 1/2-inch female NPT (FNPT) threaded connection, this coupler provides a secure, tool-side connection point in high-demand shop and plant environments. The brass and steel construction with a zinc finish resists corrosion and withstands a maximum working pressure of 232 psi. Licensed HVAC technicians, pipefitters, and industrial maintenance professionals install this type of fitting as part of pneumatic tool drops, air distribution manifolds, and service-line connections.

This coupler is rated for operating temperatures ranging from -4 degrees F to 212 degrees F, making it suitable for year-round use in both indoor and outdoor pneumatic service runs. The industrial interchange configuration is compatible with the widely adopted industrial-interchange coupler and plug standard used across manufacturing, automotive, and general-contractor applications. The threaded FNPT entry accepts standard NPT male plugs and fittings for straightforward integration into existing air lines.

Key Features

• Safety coupler design helps prevent unintended disconnection under pressure
• 3/8-inch body diameter with 1/2-inch FNPT threaded connection
• Maximum working pressure of 232 psi for demanding compressed-air applications
• Brass and steel construction with zinc finish for corrosion resistance
• Rated from -4 degrees F to 212 degrees F for broad temperature compatibility
• Industrial interchange type for wide fitment across standard pneumatic tool setups

Compatibility

Designed as an OEM-style replacement or direct addition for industrial-interchange pneumatic systems using 3/8-inch couplers with 1/2-inch FNPT threaded connections.

Installation Notes

Installation should be performed by a qualified pipefitter or industrial maintenance technician. Always depressurize and bleed the air line completely before removing or installing any coupler. Apply thread sealant tape to NPT threads in accordance with applicable pneumatic system standards. Do not exceed the rated working pressure of 232 psi during operation.
