Cejn 10 340 3402 Pneumatic Coupler 1/4 Inch Fnpt Ss

Product Description

The CEJN 10 340 3402 is a female NPT threaded pneumatic hose coupler designed for industrial compressed air and pneumatic tool applications. Built from stainless steel, this coupler features a 1/4 inch body diameter and 1/4 inch FNPT thread connection, making it a direct-connect fitting for industrial interchange systems. It is rated for a maximum working pressure of 507 psi and handles temperatures from -22 degrees F to 212 degrees F, giving it a broad operational range suited to demanding shop and field environments. Licensed HVAC technicians, pipefitters, and industrial maintenance mechanics are the typical installers.

This coupler is used in industrial pneumatic systems where standard industrial interchange quick-connect fittings are specified. It is well suited for compressed air distribution lines, pneumatic tool hookups, and manufacturing or maintenance environments that require stainless steel construction for corrosion resistance or sanitary requirements. The threaded FNPT connection allows solid, leak-resistant integration into existing pneumatic manifolds, drop lines, and tool supply assemblies.

Key Features

• Stainless steel construction provides corrosion resistance for harsh or washdown environments
• 1/4 inch FNPT thread for secure, leak-resistant connection to standard pipe fittings
• Industrial interchange design ensures broad compatibility across industrial pneumatic systems
• 507 psi maximum working pressure handles high-demand compressed air applications
• Wide temperature range: -22 degrees F to 212 degrees F
• Compact 1/4 inch body diameter suits tight installation spaces

Compatibility

Designed for use in industrial interchange pneumatic systems accepting 1/4 inch FNPT threaded couplers. Industrial interchange is one of the most widely used quick-connect standards in North American pneumatic tool and air supply applications.

Installation Notes

Installation should be performed by a qualified pipefitter or maintenance mechanic familiar with compressed air systems. Depressurize and lock out the air supply line before removing or installing any coupler fitting. Apply appropriate thread sealant or PTFE tape to the FNPT threads per standard shop practice. Verify the installed assembly does not exceed the 507 psi rated working pressure of this fitting.
