Pro-source 2555503965PRO M5 Push-to-connect Tube Fitting 5 Pack

Product Description

The PRO-SOURCE 2555503965PRO is a push-to-connect tube fitting designed for fast, tool-free connections between tubing and M5 metric threaded ports. Constructed from nickel-plated brass with a Buna-N O-ring seal, this fitting is rated to 250 psi and accepts tubing with a 3 mm outside diameter. The nickel plating provides corrosion resistance in both air and water service environments. Each package contains 5 fittings. This fitting is a practical choice for pneumatic plumbing technicians, maintenance mechanics, and fluid system installers working with compact metric-ported components.

This fitting is suited for residential and commercial compressed air systems, pneumatic control circuits, and light-duty water plumbing applications where M5 threaded ports are specified. The push-to-connect design eliminates the need for ferrules, compression sleeves, or thread sealant at the tube side, speeding up assembly and service. Typical install scenarios include pneumatic automation panels, small-bore air lines, and instrument tubing runs where 3 mm OD tubing terminates at metric-ported valves, manifolds, or actuators.

Key Features

• Push-to-connect tube side accepts 3 mm OD tubing with no additional components
• M5 metric thread on the port side for direct connection to metric-ported equipment
• Nickel-plated brass construction for corrosion resistance in air and water service
• Buna-N O-ring seal provides reliable seating across a range of service conditions
• Rated to 250 psi for use in standard compressed air and water plumbing circuits
• Sold in a pack of 5 fittings to support multi-point installations

Compatibility

Compatible with compressed air and water systems using 3 mm OD tubing and M5 metric threaded ports. Designed as a direct-connect fitting for pneumatic valves, manifolds, actuators, and instruments with M5 metric port specifications.

Installation Notes

Installation should be performed by a qualified plumbing or pneumatic systems technician. Depressurize and isolate the system completely before removing or installing fittings. Ensure tubing is cut square and deburred before inserting into the push-to-connect socket for a proper seal. Apply thread sealant or PTFE tape to the M5 male thread as required by the application and applicable codes.
