Cejn 10 320 2402 Safety Coupler 1/4 Inch Fnpt

Product Description

The CEJN 10 320 2402 is a Series 320 safety coupler designed for pneumatic hose connections in compressed air systems. Built with a brass and steel construction and finished in zinc, this threaded coupler features a 1/4 inch female NPT (FNPT) connection and 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 applications. Licensed HVAC technicians, industrial mechanics, and pneumatic system installers are the typical trades that work with this type of fitting.

This coupler fits into High Flow interchange pneumatic systems, which deliver higher air volume than standard interchange configurations. It is well suited for residential and light commercial shop environments, production floor air lines, and service van pneumatic setups where reliable quick-connect performance and safe air release are required. The safety coupler design controls air release upon disconnection, reducing hose whip risk at the point of use.

Key Features

• High Flow interchange type for increased air volume delivery
• Safety coupler design controls air release on disconnect to reduce hose whip
• 1/4 inch FNPT threaded connection for standard pipe thread compatibility
• Zinc finish over brass and steel construction for corrosion resistance
• Rated to 230 psi maximum working pressure
• Operates from -4 degrees F to 212 degrees F

Compatibility

Designed as an OEM-style replacement or direct-fit addition for High Flow interchange pneumatic hose systems using 1/4 inch FNPT threaded couplers.

Installation Notes

Installation should be performed by a qualified mechanic or pneumatic system technician. Depressurize the air line fully before removing or installing any coupler. Apply thread sealant tape or compound to the FNPT threads per standard plumbing practice to prevent air leaks. Do not overtighten threaded connections into brass fittings, as this can crack the fitting body.
