Pro-source 2556504465PRO Push-to-connect Tube Fitting 5-pack

Product Description

The PRO-SOURCE 2556504465PRO is a push-to-connect tube-to-tube fitting designed for fast, tool-free connections in compressed air and water systems. Constructed from nickel-plated brass, this fitting provides corrosion resistance and durability in demanding service environments. It accepts tubing with a 4.00 mm outside diameter and is rated for a maximum working pressure of 250 psi. Operating temperature range spans from 0 degrees F to 160 degrees F, making it suitable for a wide range of indoor plumbing, pneumatic, and light industrial applications. Each order includes 5 fittings. The Buna O-ring seals ensure reliable, leak-free performance without the need for additional sealants or threading.

This fitting is intended for tube-to-tube connections in compressed air lines and water distribution systems. It is well suited for residential and light commercial installations where quick assembly or field repair is required. Plumbers, HVAC technicians, and industrial maintenance professionals commonly use push-to-connect fittings in tight spaces where soldering or threaded connections are impractical. The nickel-plated brass construction makes this fitting compatible with both potable water and pneumatic service lines within its rated temperature and pressure limits.

Installation Notes

Installation is performed by plumbers or HVAC technicians. Before servicing any line, relieve all system pressure and shut off the water or air supply at the source. Ensure tubing ends are cut cleanly and squarely with no burrs before inserting into the fitting to achieve a proper seal. Follow applicable IPC or local plumbing codes when using in potable water applications.
