Pro-source 2556405765PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2556405765PRO is a push-to-connect tube fitting with a universal thread end, designed for quick, tool-free tube connections in compressed air and water systems. Constructed from nickel-plated brass, it handles working pressures up to 250 psi and accepts tubing with a 5 mm outside diameter. The universal thread end allows flexible installation across a variety of port configurations. Plumbers, HVAC technicians, and industrial mechanics install this fitting in pneumatic lines, light hydraulic circuits, and water supply runs where fast, reliable connections are required.

This fitting is suited for residential and light commercial applications involving compressed air distribution or water lines. It is commonly installed in pneumatic tool supply lines, HVAC condensate or water feed circuits, and equipment plumbing where push-to-connect convenience reduces installation time. The nickel plating provides corrosion resistance in both air and water service environments. Each package contains 5 fittings, making it practical for multi-connection jobs or stocking a service van.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or pipefitters. Depressurize and drain the line completely before removing any existing fitting or inserting this one. Ensure tubing is cut cleanly and squarely with no burrs before pushing into the fitting to achieve a proper seal. Verify thread engagement on the universal thread end is secure and leak-free before returning the system to service.
