Pro-source 2555604565PRO Push-to-connect Tube Fitting M5

Product Description

The PRO-SOURCE 2555604565PRO is a push-to-connect tube fitting designed for quick, tool-free connections between a tube and an M5 metric threaded port. Constructed from nickel-plated brass, it handles a maximum working pressure of 250 psi and operates across a temperature range of 0 to 160 degrees F. The fitting uses a Buna O-ring for a reliable seal. It is suitable for use with compressed air and water systems in light industrial, pneumatic, and plumbing applications. Each pack contains 5 fittings. Installation requires no special tools for the tube-side connection, making it a straightforward choice for technicians who need fast field assembly.

This fitting is used in pneumatic and fluid distribution systems where a push-to-connect tube interface meets an M5 metric threaded port. Typical applications include light industrial pneumatic tooling, automation equipment, and compressed air distribution lines. The 4 mm tube outside diameter and M5 thread size make it appropriate for small-bore pneumatic circuits. Both plumbing and instrumentation professionals install this type of fitting in residential and light commercial environments. The pack quantity of 5 units supports service kits and small-scale installations.

Compatibility

Designed for use with compressed air and water systems requiring a push-to-connect tube connection at an M5 metric threaded port with a 4 mm tube outside diameter.

Installation Notes

Shut off and depressurize the system completely before removing or installing any fitting. Insert the tube straight and fully into the fitting body until it seats to ensure a leak-free connection; do not insert at an angle. Inspect the Buna O-ring for damage before installation and replace it if any cuts or deformation are present. Verify that the M5 threaded port is clean and free of debris before threading in the fitting body.
