Pro-source 2555706865PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2555706865PRO is a push-to-connect tube fitting designed for fast, tool-free connections between tubing and universal thread ports. Constructed from nickel-plated brass, it handles working pressures up to 250 psi and is suited for compressed air and water service lines. The fitting accepts a 6 mm outside diameter tube and connects to a 1/8 inch universal thread. It is installed by plumbers, HVAC technicians, and pipefitters in light industrial, commercial, and mechanical service applications where quick-disconnect convenience and reliable sealing are required. Each package contains 5 fittings.

This fitting is commonly used in compressed air distribution systems, water service lines, and general pneumatic or fluid plumbing assemblies. The push-to-connect design allows the tube to seat and lock without ferrules or wrenches on the tube side, reducing installation time in tight spaces. The 1/8 inch universal thread port accommodates a wide range of inline components including valves, gauges, and manifolds found in residential mechanical rooms and light commercial equipment rooms.

Compatibility

Designed for use with compressed air and water systems. Accepts tubing with a 6 mm outside diameter and connects to 1/8 inch universal thread ports on valves, manifolds, gauges, and related inline components.

Installation Notes

Depressurize and lock out the system before removing or installing any fittings. Ensure tube ends are cut square and free of burrs before inserting into the push-to-connect port to achieve a proper seal. Hand-tighten the threaded side into the receiving port; use a wrench only as needed to seat the thread without overtightening brass fittings. Verify the system is leak-free at operating pressure before returning to service.
