Pro-source 2556438065PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2556438065PRO is a push-to-connect tube fitting designed to join 3/8-inch OD tubing to a 1/8-inch universal thread port. The body is nickel-plated brass, rated to 250 psi. The push-to-connect mechanism allows fast, tool-free tube insertion and a secure, leak-resistant seal without ferrules or compression nuts. The Buna-N O-ring provides reliable sealing across a broad service range. Licensed plumbers, HVAC technicians, and pneumatic system installers use this fitting in both new construction and retrofit applications where a quick, reusable connection is needed.

This fitting is suited for compressed air and water service lines in residential and light commercial systems. It is a practical choice for pneumatic control lines, instrument air, and water distribution points where 3/8-inch OD tubing meets a 1/8-inch universal thread port. Each package contains 5 fittings, making it convenient for jobs requiring multiple connection points on a single service run or manifold assembly.

Installation Notes

Installation is performed by licensed plumbers, HVAC technicians, or qualified pneumatic system technicians. Depressurize and isolate the system fully before disassembling any existing fittings or inserting new ones. Verify that the tubing OD is clean, cut square, and free of burrs before seating it into the push-to-connect port. Follow applicable codes such as the IPC or IFGC for pressurized fluid and air system connections.
