Pro-source 2557053865PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2557053865PRO is a push-to-connect tube fitting designed for fast, tool-free connections in compressed air and water systems. It features a 5/32-inch tube outside diameter and a 1/8-inch universal thread, making it a straightforward choice for technicians who need a reliable inline connection without soldering or flaring. The body is nickel-plated brass, rated to 250 psi. A Buna-N O-ring provides the sealing interface at the thread end. This fitting is installed by plumbers, HVAC technicians, and industrial maintenance techs working on pneumatic or fluid distribution lines.

This fitting suits residential and light commercial applications where compressed air or water lines require a threaded port connection combined with a push-to-connect tube termination. The universal thread allows it to fit a range of standard ported components and manifolds. Its compact size makes it practical in tight panel spaces, equipment enclosures, and tubing runs where a one-piece fitting saves time during assembly or service. Each package contains 5 fittings.

Installation Notes

Depressurize and drain the line fully before removing or installing any push-to-connect fitting. Ensure the tube end is cut cleanly and squarely with no burrs before insertion to maintain a proper seal. Thread the fitting into the port by hand first, then tighten to snug without overtorquing the brass threads. Verify there are no leaks under normal operating pressure before returning the system to service.
