Pro-source 2556438165PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2556438165PRO is a push-to-connect tube-to-universal-thread tube fitting designed for fast, tool-free connections in compressed air and water systems. Constructed from nickel-plated brass, this fitting accepts 3/8-inch OD tubing and provides a 1/4-inch universal thread port. It is rated to 250 psi, making it suitable for standard shop air lines, pneumatic control circuits, and plumbing applications. The push-to-connect design allows technicians to insert tubing and achieve a secure, leak-resistant seal without ferrules, compression nuts, or additional tools. HVAC technicians, plumbers, and industrial maintenance crews install this fitting wherever a reliable threaded-to-tube transition is needed in moderate-pressure fluid or air service.

This fitting is suited for residential and light commercial compressed air distribution, pneumatic control tubing, and water supply lines where a quick-connect transition between rigid or semi-rigid tubing and a threaded port is required. The universal thread port accommodates common thread standards, reducing the need to stock multiple thread-specific fittings. It is a practical choice for service work, panel assembly, and OEM equipment builds where fast installation and repeatability matter. Each package contains 5 fittings, allowing technicians to complete multi-connection installations from a single package.

Compatibility

Designed for use with compressed air and water systems accepting 3/8-inch OD tubing and a 1/4-inch universal thread port connection.

Installation Notes

This fitting is installed by plumbers, HVAC technicians, and industrial mechanics working on pneumatic or water lines. Depressurize and isolate the system completely before removing or installing any fittings. Ensure tubing is cut square, deburred, and fully inserted into the fitting until it seats to achieve a proper seal. To release tubing, depress the collet ring evenly while pushing the tube inward slightly before withdrawing it.
