Pro-source 2556505565PRO Push-to-connect Tube Fitting 5-pack

Product Description

The PRO-SOURCE 2556505565PRO is a push-to-connect tube-to-tube fitting designed for fast, tool-free connections in pneumatic and fluid handling systems. Constructed from nickel-plated brass, this fitting handles pressures up to 250 psi and is compatible with compressed air and water service. The push-to-connect design allows technicians to make reliable inline tube joints without threads, solder, or compression tools, reducing installation time in tight spaces. Each package contains 5 fittings, making it practical for service stock or multi-point installations. Buna-N O-rings provide the internal seal, offering good resistance to oil-contaminated air and general-purpose water lines.

This fitting is suited for residential and light commercial pneumatic plumbing, compressed air distribution lines, and water supply connections where push-to-connect convenience is required. Typical applications include HVAC equipment air controls, pneumatic actuator supply lines, and general-purpose plumbing rough-in where tube-to-tube inline connections are needed. The tube outside diameter for this fitting is 5.00 mm. Plumbers, HVAC technicians, and mechanical contractors are the primary installers for this type of fitting.

Key Features

• Push-to-connect design — no tools required for tube insertion

• Rated to 250 psi for use in compressed air and water systems
• Buna-N O-ring seal provides reliable performance in oil-contaminated air and water service
• 5.00 mm tube outside diameter compatibility
• Sold in a pack of 5 for service stock efficiency

Compatibility

Designed for use with compressed air and water systems requiring tube-to-tube push-to-connect inline fittings with a 5.00 mm tube outside diameter.

Installation Notes

Installation is performed by plumbers or HVAC technicians during pneumatic or water line assembly. Before making or breaking any connection, depressurize the line completely and shut off the water or air supply at the source valve. Ensure tube ends are cut cleanly and squarely with a tube cutter — ragged or angled cuts will compromise the O-ring seal. Verify tube outside diameter matches the fitting specification before insertion, and confirm the tube is fully seated to the stop before pressurizing the system.
