Parker 72338676 Push-to-connect Connector 3/8 in Od

Product Description

The PARKER 72338676 is a push-to-connect tube fitting connector designed for fast, tool-free tubing connections in fluid and pneumatic distribution systems. Constructed from bio-sourced Nylon 11, this connector offers a lightweight, corrosion-resistant body suited for use in compressed air, water, and compatible fluid lines. The fitting accepts 3/8 inch OD tubing and connects to a 3/8 inch NPTF threaded port, rated to 190 psi. The EPDM O-ring provides a reliable seal across a broad range of service conditions. This fitting is typically installed by HVAC technicians, plumbers, and industrial maintenance professionals working on tubing runs that require secure, repeatable connections without ferrule compression or soldering.

This connector is well suited for residential and light commercial applications including HVAC condensate lines, pneumatic control circuits, and general fluid distribution tubing. The push-to-connect mechanism allows quick field assembly and tube insertion without additional tools, making it a practical choice for panel builds, equipment hook-ups, and service replacement work. The white Nylon 11 body provides visual identification in multi-line installations. Package quantity is 10 units per package, with a minimum order quantity of 1 package.

Compatibility

Designed as an OEM-style push-to-connect replacement connector for systems using 3/8 inch OD tubing with 3/8 inch NPTF threaded ports in pneumatic and fluid distribution applications.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified industrial maintenance personnel. Before installing or removing fittings, depressurize and de-energize the system completely and confirm all fluid lines are drained or isolated. Ensure tubing is cut cleanly and squarely with no burrs before insertion into the push-to-connect port. Thread engagement into NPTF ports should follow applicable IPC or system manufacturer guidelines for thread sealant use.
