Pro-source 2555704565PRO Push-to-connect M5 Tube Fitting

Product Description

The PRO-SOURCE 2555704565PRO is a push-to-connect tube-to-metric-thread fitting designed for quick, tool-free tubing connections in pneumatic and fluid systems. Constructed from nickel-plated brass, it accepts 4 mm outside diameter tubing and threads into M5 metric ports. The fitting is rated to 250 psi and uses a Buna-N O-ring seal to maintain a leak-free connection under pressure. Plumbers, pipefitters, and pneumatic system technicians install this type of fitting where fast, reliable tube terminations are required without the need for ferrules, wrenches, or solder.

This fitting is suited for compressed air and water service in both light industrial and commercial applications. Typical installations include pneumatic control panels, solenoid valve manifolds, and small-bore tubing runs where M5 threaded ports are used as the inlet or outlet connection. The push-to-connect design allows tubing to be inserted and locked in place in a single motion, making it practical for tight spaces or high-volume assembly work. Each package contains 5 fittings.

Key Features

• Push-to-connect design accepts 4 mm OD tubing without tools or additional fittings
• M5 metric thread connection for direct installation into M5 threaded ports
• Nickel-plated brass construction for corrosion resistance in air and water service
• Rated to 250 psi for reliable performance in compressed air applications
• Buna-N O-ring seal provides leak-free performance across typical service temperatures
• Packaged in a quantity of 5 fittings per pack

Compatibility

Designed for use with compressed air and water systems utilizing 4 mm OD tubing and M5 metric threaded ports, consistent with standard pneumatic and fluid control applications.

Installation Notes

Depressurize and drain the system completely before removing or installing any fittings. Insert tubing squarely into the collet until it seats fully to ensure proper grip and seal. To release tubing, depress the collet ring while pulling the tube out. Thread engagement should be made by hand first to avoid cross-threading M5 ports; verify the correct metric thread pitch before installation.
