Pro-source 2555714865PRO Push-to-connect Tube Fitting 1/4in Od

Product Description

The PRO-SOURCE 2555714865PRO is a push-to-connect tube-to-universal-thread fitting designed for fluid and pneumatic line connections in HVAC, plumbing, and light industrial applications. It accepts 1/4-inch OD tubing on the push-to-connect end and terminates in a 1/8-inch universal thread on the other side. The body is nickel-plated brass with a Buna O-ring seal, rated to 250 psi maximum working pressure. The fitting operates across a temperature range of 0 degrees F to 160 degrees F. Installation requires no tools on the tube-insert side, making it well suited for quick field connections and tight-space service work.

This fitting is commonly used in residential and light commercial HVAC systems, refrigeration equipment, compressed air lines, and pneumatic control circuits where a fast, reliable tube-to-thread transition is needed. It is appropriate for any application where 1/4-inch OD tubing must connect to a 1/8-inch universal thread port. HVAC technicians, plumbers, and fluid-system mechanics regularly use this style of fitting during new installations and service calls. Each package contains 5 fittings, making it convenient for multi-point installations or keeping service stock on the truck.

Installation Notes

De-pressurize and lock out the system before removing or installing any line fittings. Ensure tubing is cut cleanly and squarely with no burrs before inserting into the push-to-connect end — burrs can damage the O-ring and cause leaks. Confirm thread engagement is secure before restoring system pressure. Licensed mechanical and HVAC contractors should verify that the fitting meets local code requirements for the specific fluid and pressure application.
