Pro-source 2556411963PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2556411963PRO is a push-to-connect tube fitting designed for fast, tool-free connections in compressed air and water systems. The fitting accepts 1/2 inch OD tubing on the tube side and terminates in a 1/4 inch universal thread on the other end. Constructed from nickel-plated brass, it is rated to 250 psi. The push-to-connect mechanism allows the tubing to seat and seal without wrenches or solvents, reducing installation time on pneumatic and fluid distribution lines. An included Buna-N O-ring provides the sealing interface. This fitting is typically installed by HVAC technicians, plumbers, and industrial maintenance professionals working on compressed air distribution or water lines.

This fitting is suited for residential and light commercial applications where compressed air lines or water supply tubing requires a quick, secure connection point. The universal thread end provides broad compatibility with standard port fittings on equipment, manifolds, and valve bodies. The push-to-connect end accommodates 1/2 inch OD tubing commonly used in pneumatic control circuits, small-bore compressed air drops, and water supply runs. Each package contains 3 fittings, making it practical to stock multiples for service calls or panel builds.

Installation Notes

Shut off and depressurize the system before removing or installing fittings. Ensure tubing is cut cleanly and squarely, free of burrs, before inserting into the push-to-connect end to achieve a proper seal. Verify thread compatibility at the universal thread port before final assembly. This fitting should be installed by a qualified technician familiar with compressed air or plumbing system requirements in the jurisdiction of use.
