Cejn 10 410 5402 Pneumatic Hose Coupling 1/4 Fnpt

Product Description

The CEJN 10 410 5402 is a high flow pneumatic hose coupling connector designed for compressed air and gas distribution systems. Built from zinc-finished steel, this threaded connector features a 1/4 inch female NPT thread and a 3/8 inch body diameter. It is rated for a maximum working pressure of 232 psi and operates across a temperature range of -4 degrees F to 212 degrees F, making it suitable for both indoor and outdoor industrial service. HVAC technicians, pipefitters, and pneumatic system installers use this type of fitting to connect air hoses and tools within high flow interchange systems.

This connector fits into high flow interchange pneumatic systems and is appropriate for light industrial, commercial, and trade service applications. The 1/4 inch FNPT thread is a common size in compressed air distribution, compatible with standard NPT-threaded ports on air compressors, manifolds, and tool lines. The Series 410 designation identifies it within the CEJN high flow product family. It is sold individually and is well suited for service truck kits, shop air systems, and field repair inventory.

Installation Notes

Installation is performed by pipefitters, HVAC technicians, or qualified pneumatic system technicians. Always depressurize the air line and bleed residual pressure before removing or installing any pneumatic fitting. Apply thread sealant tape or compound rated for compressed air to the NPT threads before assembly to ensure a leak-free connection. Follow applicable OSHA compressed air safety guidelines and local mechanical codes during installation.
