Pro-source 2555651465PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2555651465PRO is a push-to-connect tube-to-universal-thread fitting designed for fast, tool-free tube connections in compressed air and water systems. Constructed from nickel-plated brass, it accepts 5/16-inch OD tubing and terminates to a 1/4-inch universal thread. The fitting is rated to 250 psi maximum working pressure and handles temperatures from 0 degrees F to 160 degrees F. The Buna O-ring seal provides a reliable, leak-resistant connection. Each package contains 5 fittings. Plumbers, HVAC technicians, and industrial service professionals install these in line sets, pneumatic circuits, and general fluid-handling assemblies where a quick-connect interface is preferred over compression or flare fittings.

This fitting is suited for both residential and light commercial applications involving compressed air distribution and water service lines. The push-to-connect design allows tubing to seat and lock without threading or crimping tools, making it practical for tight spaces or high-volume installations. The universal thread end connects to standard ported components, valves, and manifolds. Each pack of 5 provides enough quantity for multi-point installations or service call restocking.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or qualified service professionals. Before servicing any line, depressurize the system completely and shut off the fluid supply. Ensure tubing cut ends are clean, square, and free of burrs before inserting into the push-to-connect port. Verify the thread end is properly engaged and seated to prevent leaks under pressure.
