Cejn 10 410 2405 Pneumatic Safety Coupler 1/2 Fnpt

Product Description

The CEJN 10 410 2405 is a pneumatic safety coupler designed for high-flow compressed air systems in industrial and trade environments. Built with a brass and steel construction and a zinc finish, it features a 1/2 inch female NPT (FNPT) threaded connection and a 3/8 inch body diameter. The coupler is rated for a maximum working pressure of 232 psi and handles temperatures from -4 degrees F to 212 degrees F, making it suitable for demanding shop, manufacturing, and maintenance applications. Installation is handled by maintenance technicians, pipefitters, or industrial mechanics working with compressed air distribution systems.

This safety coupler is used in high-flow pneumatic systems where a reliable, thread-connected quick-disconnect fitting is required. The High Flow interchange type supports higher air volume compared to industrial-standard couplers, which reduces pressure drop and improves tool performance. Typical applications include air compressor outlets, drop lines, and pneumatic tool connections in commercial shops, production facilities, and heavy-maintenance environments. The FNPT thread allows direct connection to standard pipe-threaded ports and fittings.

Key Features

• High Flow interchange type for reduced pressure drop at the coupling point
• 1/2 inch female NPT thread for direct connection to standard pipe-threaded ports
• 3/8 inch body diameter rated to 232 psi maximum working pressure
• Brass and steel construction with zinc finish for corrosion resistance
• Operating range of -4 degrees F to 212 degrees F suits most shop environments
• Safety coupler design helps prevent unintended disconnection under pressure

Compatibility

Designed for use in High Flow interchange pneumatic systems. Compatible with High Flow interchange-style plugs and couplers. Verify interchange type and thread size against existing system fittings before installation.

Installation Notes

Depressurize the compressed air line completely before installing or removing any pneumatic coupling. Apply thread sealant tape or compound appropriate for pneumatic service to the FNPT threads per the fitting manufacturer guidelines. Tighten to manufacturer-recommended engagement depth without over-torquing the brass body. Installation should follow applicable OSHA and local compressed air safety standards.
