The PRO-SOURCE 2559004365PRO is a push-to-connect tube to stem tube fitting designed for fast, tool-free connections in pneumatic and fluid-transfer applications. Constructed from nickel-plated brass, it handles a maximum working pressure of 250 psi and operates across a temperature range of 0 degrees F to 160 degrees F. The fitting uses a Buna O-ring for a reliable seal. It is suited for compressed air and water service and is typically installed by HVAC technicians, plumbers, or industrial maintenance professionals working on low-pressure fluid or pneumatic lines.
This fitting is appropriate for residential and light commercial applications involving compressed air distribution or water lines. The push-to-connect design allows for quick installation and removal without soldering or threading tools. The tube outside diameter measures 3.00 mm and the stem outside diameter measures 4.00 mm. Each package contains 5 fittings, making it practical for multi-point installations or service kit restocking.
Designed for use with compressed air and water systems requiring a tube-to-stem push-to-connect fitting with a 3.00 mm tube outside diameter and 4.00 mm stem outside diameter.
Installation is performed by depressing the collet and inserting the tubing until it seats fully. Before servicing any line, de-pressurize the system and shut off the supply valve. Verify that tubing outside diameter matches the fitting specification before assembly. Follow applicable local plumbing or mechanical codes when integrating into pressurized water or compressed air systems.
