Coilhose Pneumatics CL680404 Push-to-connect Fitting

Product Description

The COILHOSE PNEUMATICS CL680404 is a push-to-connect tube fitting connector designed for use in pneumatic plumbing systems. It features a 1/4 inch NPT thread and accepts tubing with a 1/4 inch outside diameter. The body combines glass-reinforced nylon with nickel-plated brass internal components, delivering a rated maximum working pressure of 225 psi. This fitting provides a fast, tool-free tube connection suitable for compressed air lines and light fluid transfer circuits. HVAC technicians, plumbers, and industrial service pros install these fittings where quick tube terminations are needed without soldering or ferrule compression.

The CL680404 fits standard 1/4 inch OD tubing in residential and light commercial pneumatic control and compressed air distribution systems. Its NPT thread accommodates standard ported fittings and manifold ports found across a wide range of pneumatic equipment. The push-to-connect design speeds up installation in tight spaces and reduces assembly time on multi-connection runs. The operating temperature range of -40 degrees F to 170 degrees F makes it suitable for both outdoor and indoor service environments.

Key Features

• Push-to-connect design allows fast, tool-free tube insertion and removal
• Rated to 225 psi maximum working pressure for reliable compressed air service
• 1/4 inch NPT thread for compatibility with standard pneumatic ports and manifolds
• Glass-reinforced nylon and nickel-plated brass construction resists corrosion and mechanical wear
• Wide temperature range from -40 degrees F to 170 degrees F suits varied service conditions

Compatibility

Designed as an OEM-style push-to-connect replacement connector for standard 1/4 inch OD tubing with 1/4 inch NPT ported fittings in pneumatic compressed air and control systems.

Installation Notes

Installation is typically performed by HVAC technicians, plumbers, or pneumatic system technicians. Always depressurize and lock out the air supply before connecting or disconnecting fittings. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect port to achieve a proper seal. Verify that thread sealant or PTFE tape is applied to the NPT threads per standard pneumatic piping practice before assembly.
