Pro-source 2555806465PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2555806465PRO is a push-to-connect tube-to-tube fitting designed for quick, tool-free connections in compressed air and water plumbing systems. Constructed from nickel-plated brass, this fitting provides corrosion resistance and durability in demanding service environments. It is rated to 250 psi and features a Buna-N O-ring seal that maintains a leak-free connection under pressure. The compact form factor makes it well-suited for tight-space installations in pneumatic panels, fluid distribution manifolds, and equipment plumbing runs. Licensed plumbers, pipefitters, and mechanical technicians are the primary installers of this type of fitting.

This fitting connects tube to tube using a push-to-connect mechanism, eliminating the need for flare tools, solder, or compression sleeves on compatible tubing. It is rated for use with compressed air and water service. The outside diameter sizing of 6 mm by 4 mm makes it appropriate for small-bore pneumatic and fluid lines commonly found in light industrial and commercial mechanical systems. Each package contains 5 fittings, and the minimum order quantity is 1 package.

Compatibility

Designed for use with compressed air and water systems requiring tube-to-tube push-to-connect fittings with a 6 mm by 4 mm outside diameter tube connection.

Installation Notes

Installation is performed by plumbers, pipefitters, or qualified mechanical technicians. Depressurize and isolate the line completely before removing or installing fittings. Ensure tube ends are cut cleanly and squarely with no burrs, as a poor tube end is the leading cause of push-to-connect seal failure. Verify tubing outside diameter is compatible before seating the tube into the fitting body.
