Pro-source 2558503365PRO Push-to-connect Tube Fitting 5-pack

Product Description

The PRO-SOURCE 2558503365PRO is a push-to-connect tube-to-tube fitting designed for fast, tool-free connections in pneumatic and fluid systems. Constructed from nickel-plated brass, it handles a maximum working pressure of 250 psi and operates across a temperature range of 0 to 160 degrees F. The Buna O-ring seal ensures a leak-resistant connection on 3.00 mm outside diameter tubing. This fitting is sold in a pack of 5 and is typically installed by HVAC technicians, plumbers, and industrial maintenance professionals working with compressed air or water lines.

This fitting is suited for light commercial and residential applications involving compressed air distribution, water supply lines, and similar low-pressure fluid systems. Its push-to-connect design eliminates threading or soldering, making it a practical choice for service calls and equipment installations where speed and reliability matter. The 3.00 mm OD tube compatibility keeps it well-suited for small-diameter pneumatic control lines and instrumentation tubing commonly found in HVAC control systems and light industrial equipment.

Installation Notes

Installation is typically performed by licensed HVAC technicians, plumbers, or qualified maintenance personnel. Before servicing any fitting, isolate and depressurize the line completely. Ensure tubing is cut cleanly and squarely and is free of burrs before inserting into the fitting to achieve a proper seal. Verify that all connections are leak-free before returning the system to service.
