Cejn 10 320 5452 Pneumatic Coupling 1/4 in Mnpt

Product Description

The CEJN 10 320 5452 is a steel pneumatic hose coupling connector designed for compressed-air and pneumatic tool applications. It features a 1/4-inch male NPT (MNPT) threaded connection and a 1/4-inch body diameter, built to the High Flow interchange standard. The zinc-finished steel body 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 demanding shop and industrial environments. Licensed HVAC techs, maintenance mechanics, and pneumatic system installers rely on this type of connector for reliable quick-connect service on air lines and tool drops.

This connector is appropriate for use in residential, commercial, and light industrial pneumatic systems where High Flow interchange-style couplings are the shop standard. It threads directly onto air hoses, compressor outlets, tool inlets, or manifold ports using standard NPT fittings. The threaded connection type supports secure, leak-resistant assembly in stationary and portable compressed-air setups. It is sold individually, making it practical for single-point repairs or small-quantity restocks.

Key Features

• High Flow interchange standard for compatibility with High Flow pneumatic systems
• 1/4-inch MNPT threaded connection for secure, leak-resistant attachment
• 230 psi maximum working pressure rated for demanding compressed-air service
• Operating temperature range: -4 degrees F to 212 degrees F
• Steel construction with zinc finish for corrosion resistance
• 1/4-inch body diameter — compact form factor for tight installations

Compatibility

Designed as a High Flow interchange-style pneumatic connector for use with 1/4-inch MNPT threaded pneumatic hose and tool connections in compressed-air systems.

Installation Notes

Installation is performed by maintenance mechanics or pneumatic system technicians. Always depressurize and bleed the air line completely before removing or installing any pneumatic fitting. Apply thread sealant tape or liquid sealant appropriate for compressed-air service on the MNPT threads before assembly. Torque the connector hand-tight plus the additional turns recommended by the sealant manufacturer — do not over-tighten steel-threaded fittings into softer-material ports.
