Pro-source 2556404765PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2556404765PRO is a push-to-connect tube fitting designed for quick, tool-free tube connections to a universal thread port. Constructed from nickel-plated brass, it accepts a 4 mm outside diameter tube and is rated to 250 psi. The universal thread configuration makes it compatible with a wide range of threaded ports without requiring thread-specific adapters. This fitting is suited for plumbing, HVAC, and compressed air system assemblies where fast, reliable connections are required. Licensed trade professionals and experienced technicians install this type of fitting in both new construction and service applications.

This fitting is designed for use with compressed air and water lines. The push-to-connect mechanism allows tube insertion without ferrules, nuts, or separate thread adapters, reducing assembly time in tight spaces. The nickel-plated brass body resists corrosion in both wet and dry service environments. A Buna-N O-ring provides the primary seal at the thread interface. This SKU is packaged in a quantity of 5 units per package, making it practical for multi-point installations or service stock.
