Pro-source 2555638065PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2555638065PRO is a push-to-connect tube fitting designed for quick, tool-free connections in compressed air and water systems. Constructed from nickel-plated brass, this fitting accepts 3/8 inch OD tubing and threads into a 1/8 inch universal thread port. It is rated to 250 psi, making it suitable for typical pneumatic and fluid distribution lines found in commercial and industrial facilities. The push-to-connect mechanism allows a technician to insert tubing and achieve a secure, leak-resistant seal without additional fittings or clamps. A Buna-N O-ring provides the internal seal. This fitting is installed by HVAC technicians, plumbers, and general maintenance professionals working on compressed air distribution or water supply lines.

This fitting is used in both commercial and light industrial settings where compressed air or water lines require fast, reliable connections. It is well suited for instrument air lines, pneumatic control circuits, and low-pressure water distribution. The universal thread type allows broad compatibility across common port configurations. Each package contains 5 fittings, making it practical for service calls requiring multiple connection points or for stocking service vans and shop inventory.

Installation Notes

Shut off and depressurize the air or water line completely before replacing or installing any push-to-connect fitting. Ensure tubing is cut cleanly and squarely and that the OD is within the specified 3/8 inch tolerance before insertion. Inspect the Buna-N O-ring seat for debris before threading the fitting into the port. Installations on compressed air systems should conform to applicable OSHA and local safety requirements for pressurized piping.
