Pro-source 2555506565PRO Push-to-connect Fitting M5 6mm

Product Description

The PRO-SOURCE 2555506565PRO is a push-to-connect tube fitting designed to transition between a standard tube connection and an M5 metric thread port. The body is nickel-plated brass, offering corrosion resistance suitable for compressed air and water service. The fitting accepts 6 mm outside diameter tubing and is rated to 250 psi. A Buna-N O-ring provides the primary seal at the threaded end. This type of fitting is commonly installed by HVAC technicians, plumbers, and pneumatic systems technicians working with metric-ported equipment and standard soft tubing in light industrial or commercial environments.

This fitting is suited for compressed air distribution lines and water service applications where a quick, tool-free tube termination at an M5 metric threaded port is required. The push-to-connect mechanism allows fast assembly and disassembly without additional ferrules or compression sleeves, making it practical in tight spaces or systems that require periodic service. It ships in a package quantity of five, which suits small repair jobs or multi-point installations on a single manifold or equipment panel.

Key Features

• Nickel-plated brass body resists corrosion in compressed air and water service
• Push-to-connect design allows tool-free tube insertion and removal
• Accepts 6 mm outside diameter tubing
• M5 metric thread on the mating port end
• Buna-N O-ring seal at the threaded connection
• Rated to 250 psi working pressure

Compatibility

Designed for use with 6 mm OD tubing in compressed air and water systems requiring an M5 metric threaded port connection. Compatible with standard push-to-connect tubing in pneumatic and fluid-handling circuits.

Installation Notes

Installation is typically performed by HVAC technicians or plumbers familiar with pneumatic or fluid-control piping. Before installation, depressurize and isolate the system completely. Ensure the M5 threaded port is clean and free of debris before threading the fitting in by hand; apply appropriate thread sealant per system requirements and applicable codes. Tubing must be cut squarely and deburred before insertion to ensure a reliable push-to-connect seal.
