Cejn 10 320 5402 Pneumatic Coupling 1/4 in Fnpt High Flow

Product Description

The CEJN 10 320 5402 is a threaded pneumatic hose coupling connector designed for compressed air and pneumatic tool circuits. Built from zinc-finished steel, this connector uses a 1/4 inch female NPT (FNPT) thread and features a 1/4 inch body diameter. It is rated for a maximum working pressure of 230 psi and handles temperatures from -4 degrees F to 212 degrees F, making it suitable for a wide range of shop and industrial pneumatic service environments. HVAC technicians, plumbers, and general trade professionals use this type of fitting when assembling or servicing pneumatic tool lines.

This coupling is intended for use in high-flow interchange pneumatic systems where quick-connect or threaded connector fittings are required at compressors, tool drops, or service manifolds. The FNPT thread type allows direct connection to standard pipe-threaded ports found on air compressors, blow guns, impact wrenches, and similar pneumatic equipment. It is suited for both light commercial and industrial compressed air systems operating within the rated pressure and temperature limits.

Key Features

• High-flow interchange connector design for improved air delivery
• 1/4 inch FNPT threaded connection for compatibility with standard pipe-threaded ports
• Steel construction with zinc finish for corrosion resistance in shop environments
• Rated to 230 psi maximum working pressure
• Operating temperature range of -4 degrees F to 212 degrees F

Compatibility

Designed as an OEM-style replacement or service connector for high-flow interchange pneumatic systems using 1/4 inch FNPT threaded fittings.

Installation Notes

Installation should be performed by a qualified technician following applicable compressed air safety practices. Depressurize the air line completely before removing or installing any pneumatic coupling. Apply appropriate thread sealant to FNPT threads to prevent air leakage. Verify that the system operating pressure does not exceed the 230 psi rated maximum of this fitting.
