Pro-source 2557003965PRO Push-to-connect M5 Fitting

Product Description

The PRO-SOURCE 2557003965PRO is a push-to-connect tube fitting designed for tube-to-metric-thread connections in compressed air and water systems. The body is nickel-plated brass, rated for a maximum working pressure of 250 psi and a temperature range of 0 degrees F to 160 degrees F. The fitting accepts a tube with a 3.00 mm outside diameter and connects to an M5 metric thread port. A Buna O-ring provides the sealing element. Plumbers, HVAC technicians, and pneumatic system technicians use this fitting when transitioning from a small-bore tube to an M5 threaded port on valves, manifolds, or equipment panels.

This fitting is suited for residential and light commercial applications involving compressed air lines or water distribution where M5 metric threaded ports are present. Typical install scenarios include pneumatic control panels, solenoid valve manifolds, and instrumentation tubing. The push-to-connect design allows for tool-free tube insertion, making it practical for tight spaces or high-volume termination work. Each package contains 5 fittings with a minimum order quantity of 1 package.

Key Features

• Push-to-connect design allows tool-free tube insertion and removal
• Nickel-plated brass construction resists corrosion in wet and pneumatic environments
• Rated to 250 psi maximum working pressure
• Operates from 0 degrees F to 160 degrees F
• Buna O-ring sealing element compatible with compressed air and water media
• M5 metric thread port connection for compatibility with metric-threaded equipment

Compatibility

Designed for use with compressed air and water systems utilizing 3.00 mm outside diameter tubing and M5 metric threaded ports on valves, manifolds, or pneumatic equipment.

Installation Notes

Installation should be performed by a qualified plumbing or pneumatic systems technician. Depressurize and isolate the line completely before removing or installing any fitting. Verify that the tube outside diameter is 3.00 mm and the mating port thread is M5 before insertion. Do not exceed the rated working pressure or temperature limits of the fitting.
