Pro-source 2555511963PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2555511963PRO 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 1/2-inch OD tubing on the push-to-connect end and terminates in a 1/4-inch universal thread. Rated to 250 psi, this fitting is suited for moderate-pressure pneumatic and fluid-handling lines. The Buna-N O-ring provides a reliable seal across the connection. Plumbers, HVAC technicians, and mechanical contractors install this type of fitting where a quick, repeatable tube connection to a threaded port is needed without soldering or compression tools.

This fitting is used in residential and light commercial applications involving compressed air distribution, water supply, and general fluid-transfer plumbing. The push-to-connect design allows tubing to be inserted and locked without additional fittings or sealant at the tube end, making it a practical choice for tight spaces or retrofit work. It is compatible with systems handling compressed air or water up to 250 psi. Each package contains 3 fittings, with a minimum order quantity of 1 package.

Compatibility

Designed for use with compressed air and water systems requiring a 1/2-inch OD tube connection to a 1/4-inch universal threaded port.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or pipefitters. Before servicing any line, depressurize and isolate the system fully. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect end, as debris or irregular cuts can compromise the O-ring seal. Verify thread engagement meets applicable plumbing or mechanical codes such as IPC or ASME B31 standards for the system type.
