Pro-source 2556438265PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2556438265PRO is a push-to-connect tube-to-universal-thread tube fitting designed for quick, tool-free tube connections in compressed air and water systems. Constructed from nickel-plated brass, this fitting accepts 3/8 inch OD tubing and provides a 1/2 inch universal thread connection. It is rated to 250 psi, making it suitable for standard compressed air distribution and low-pressure water plumbing applications. The Buna-N O-ring seat ensures a reliable, leak-resistant seal. Plumbers, pipefitters, and HVAC technicians install these fittings where fast, repeatable connections are needed without crimping or soldering tools.

This fitting is used in residential and light commercial compressed air lines, water supply tubing runs, and pneumatic control systems. The push-to-connect design allows a technician to insert compatible 3/8 inch OD tubing and achieve an immediate pressure-rated seal. Its universal thread end accepts standard threaded ports on manifolds, valves, solenoids, and similar components. The nickel-plated brass construction resists corrosion in both air and water service environments. This SKU is sold in a package quantity of 5 units.

Installation Notes

Depressurize and isolate the line before removing or installing any push-to-connect fitting. Ensure tubing is cut cleanly and squarely with no burrs before insertion to maintain a proper O-ring seal. This type of fitting is typically installed by plumbers, pipefitters, or HVAC technicians following applicable local plumbing and mechanical codes. Do not exceed the 250 psi pressure rating or use this fitting in applications outside compressed air or water service without verifying fluid compatibility with Buna-N and nickel-plated brass.
