Pro-source 2557514865PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2557514865PRO is a push-to-connect tube fitting with a female NPT port on each tube connection, designed for fast, tool-free tubing connections in compressed air and water systems. The fitting is manufactured from nickel-plated brass and rated to 250 psi. It accepts 1/4 inch outside-diameter tubing and threads into a 1/8 inch NPTF female port. The Buna-N O-ring provides a reliable seal across typical operating conditions. Plumbers, HVAC technicians, and mechanical contractors use this fitting where quick tube connections to threaded ports are needed without soldering or ferrule compression.

This fitting is suited for residential and light commercial applications involving compressed air distribution lines and water supply tubing. Its push-to-connect design speeds up installation in tight spaces where wrench access is limited. The nickel-plated brass construction resists corrosion in damp environments. Typical install scenarios include pneumatic control lines, instrument air drops, and small-bore water supply connections at equipment panels or manifolds. Package quantity is 5 per unit, making it practical for multi-point installations in a single service call.

Installation Notes

Installation is performed by plumbers, HVAC technicians, or pipefitters working on low-pressure pneumatic or water lines. Depressurize and drain the system fully before removing any existing fittings or inserting new connections. Confirm tubing is cut square and free of burrs before inserting into the push-to-connect collet to ensure a proper seal. Thread the NPTF port connection with appropriate thread sealant per applicable IPC or IFGC guidelines for the medium being conveyed.
