Pro-source 2556406865PRO Push-to-connect Tube Fitting 5pk

Product Description

The PRO-SOURCE 2556406865PRO 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. The body is nickel-plated brass, rated to 250 psi, and accepts tubing with a 6 mm outside diameter. The universal thread end allows broad compatibility across common fitting configurations. This fitting is installed by HVAC technicians, plumbers, and pneumatic system technicians in both residential and light commercial applications where fast, reliable tube terminations are required. Each package contains 5 fittings.

This fitting is suited for compressed air lines and water service applications. Its push-to-connect design eliminates the need for ferrules, compression sleeves, or thread sealing on the tube side, making it appropriate for panel installations, equipment connections, and service repairs where speed and access are priorities. The Buna-N O-ring provides a secure seal across a range of operating conditions common in HVAC and pneumatic plumbing work.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified pneumatic system technicians. Before servicing any line, depressurize the system completely and shut off the water or air supply at the source. Ensure tubing is cut cleanly and squarely, and that the tube outside diameter matches the 6 mm specification before inserting into the fitting. Follow applicable codes including the International Plumbing Code for water service or relevant OSHA and ANSI standards for compressed air systems.
