Pro-source 2555703965PRO Push-to-connect Fitting M5 5-pack

Product Description

The PRO-SOURCE 2555703965PRO is a push-to-connect tube fitting with an M5 metric thread connection, designed for fast, tool-free tube installation in pneumatic and fluid-handling systems. The body is nickel-plated brass with a Buna-N O-ring seal, rated to 250 psi working pressure. The fitting accepts a 3mm outside diameter tube and threads directly into M5 metric ports. Sold in a 5-piece package, this fitting is a standard choice for maintenance technicians, pneumatic system assemblers, and plumbing professionals working on compressed air or water distribution lines. Its push-to-connect design eliminates the need for ferrules or compression sleeves, speeding up assembly and field repairs.

This fitting is suited for residential, commercial, and light industrial applications where compressed air or water lines are routed through equipment using M5 metric threaded ports. Typical installations include pneumatic control panels, automation equipment, small-bore compressed air networks, and low-pressure water circuits. The 3mm OD tube size is common in instrumentation and light pneumatic tooling. The nickel-plated brass construction resists corrosion in both dry air and water service, making it a durable choice across a range of environments.

Compatibility

Designed for use with compressed air and water systems requiring M5 metric thread connections and 3mm outside diameter tubing.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or pneumatic systems technician. Before installing or removing any fitting, shut off and depressurize the supply line completely. Verify that the tube OD matches the 3mm specification and that the receiving port is a clean, undamaged M5 metric thread before hand-tightening. Do not overtighten the threaded end; follow the equipment manufacturer torque guidance for M5 metric ports.
