Pro-source 2559006465PRO Push-to-connect Tube Stem Fitting

Product Description

The PRO-SOURCE 2559006465PRO is a push-to-connect tube to stem tube fitting designed for fast, tool-free connections in compressed air and water systems. Constructed from nickel-plated brass, it offers corrosion resistance and durability in demanding trade environments. The fitting connects a tube with a 4.00 mm outside diameter to a stem with a 6.00 mm outside diameter. It is rated for a maximum working pressure of 250 psi and handles temperatures from 0 degrees F to 160 degrees F. Licensed plumbers, pipefitters, and HVAC technicians install this type of fitting in both residential and light commercial fluid and pneumatic service lines.

This fitting is suited for use with compressed air and water lines in a variety of installation scenarios, including pneumatic control systems, HVAC pneumatic actuators, and low-pressure water distribution applications. The push-to-connect design eliminates the need for threaded assembly or solder, making it a practical choice for quick repairs and new installations. It is sold in a package quantity of 5, which suits both service calls and small-scale installation projects. The Buna O-ring seal provides reliable performance across the rated temperature and pressure range.
