Parker 72338668 Push-to-connect Connector 3/8 Od

Product Description

The PARKER 72338668 is a push-to-connect connector tube fitting designed for fast, tool-free tubing connections in fluid and pneumatic distribution systems. Made from bio-sourced Nylon 11, this fitting accepts 3/8 inch OD tubing and connects via a 1/4 inch NPTF threaded port. It is rated to 190 psi, making it suitable for moderate-pressure pneumatic and fluid transfer lines. The white Nylon 11 body offers good chemical resistance and a sustainable material profile. EPDM o-rings provide a reliable seal across a broad temperature range. Plumbers, HVAC technicians, and pneumatic system installers use this fitting to terminate or transition tubing runs quickly without soldering or compression tooling.

This fitting is suited for residential and light commercial applications including pneumatic control lines, condensate and fluid transfer tubing, and instrumentation plumbing. The push-to-connect design reduces installation time on new construction and retrofit jobs. It is packaged in a quantity of 10 units per pack, making it practical for service vans and panel shop builds where multiple connection points are common. The NPTF thread type ensures a pressure-tight mechanical seal at the port without requiring additional sealant tape in many applications, though following local plumbing code practice is recommended.

Compatibility

Designed as an OEM-style push-to-connect connector for use with 3/8 inch OD tubing in pneumatic, fluid transfer, and instrumentation plumbing systems utilizing 1/4 inch NPTF threaded ports.

Installation Notes

Installation is performed by licensed plumbers or qualified pneumatic system technicians. Depressurize and isolate the system completely before removing or installing any fittings. Ensure tubing is cut cleanly and squarely and deburred before insertion to achieve a proper seal. Verify that the threaded port is clean and free of debris before engagement, and follow applicable IPC or local plumbing code requirements regarding thread sealant use with NPTF connections.
