Coilhose Pneumatics CL640404 Union Fitting 1/4 Inch Od

Product Description

The COILHOSE PNEUMATICS CL640404 is a push-to-connect union tube fitting designed for joining two equal-diameter pneumatic lines without tools. Made from glass-reinforced nylon, it handles pressures up to 225 psi and accepts tubing with a 1/4 inch outside diameter. The push-to-connect design allows fast, secure connections and disconnections in compressed air distribution systems, machine plumbing, and fluid-handling assemblies. This fitting is installed by technicians working on pneumatic control circuits, automation equipment, and air supply lines in light industrial and commercial environments.

This union fitting is suited for pneumatic tubing runs where two sections of 1/4 inch OD tubing need to be joined inline. Common applications include compressed air distribution, pneumatic control panels, and industrial machine plumbing. The glass-reinforced nylon construction makes it a practical choice for environments where lightweight, corrosion-resistant fittings are preferred over metal alternatives. It is sold individually with a minimum order quantity of 5 units.

Key Features

• Push-to-connect design allows tool-free tube insertion and release
• Rated to 225 psi for reliable performance in compressed air systems
• Glass-reinforced nylon body resists corrosion and reduces weight
• Accepts 1/4 inch OD tubing on both ends for inline union connections
• Compact construction fits tight plumbing spaces in panels and machinery

Compatibility

Designed as an OEM-style replacement union fitting for pneumatic systems using 1/4 inch OD tubing in compressed air and fluid-handling applications.

Installation Notes

Depressurize and bleed the air line completely before removing or installing push-to-connect fittings. Cut tubing square and free of burrs before insertion to ensure a proper seal. Push the tube firmly into the fitting until it seats fully against the internal collet. To release, press the collet ring inward while withdrawing the tube. Follow applicable pneumatic system codes and equipment manufacturer guidelines for maximum working pressure and tubing compatibility.
