Pro-source 2555906665PRO Push-to-connect Tube Fitting 5-pack

Product Description

The PRO-SOURCE 2555906665PRO is a push-to-connect tube-to-tube fitting designed for fast, tool-free connections in compressed air and water plumbing systems. Constructed from nickel-plated brass, it delivers a rated working pressure of 250 psi and uses a Buna-N O-ring for a reliable, leak-resistant seal. The 6.00 mm outside diameter tube sizing makes it suitable for small-bore pneumatic and fluid distribution lines. Licensed plumbers and pipefitters install these fittings in both residential and light commercial service environments where quick assembly and secure tube retention are priorities. Each order includes 5 fittings.

This fitting is used in compressed air distribution lines and water service applications where push-to-connect technology is preferred over threaded or compression-style joints. It is well-suited for pneumatic tool supply runs, HVAC equipment drain or supply connections, and process plumbing where 6.00 mm OD tubing is specified. The nickel-plated brass construction provides corrosion resistance appropriate for both indoor air lines and potable or non-potable water circuits. The tube-to-tube configuration joins two tube ends inline without requiring additional fittings or adapters.

Installation Notes

Shut off and depressurize the supply line fully before removing or installing any push-to-connect fitting. Cut tubing squarely and deburr the end before insertion to ensure full seating and a leak-free seal. Verify the tube OD matches the fitting specification before assembly; mismatched tube sizing will compromise seal integrity. Installation should comply with applicable plumbing codes including IPC provisions for the intended fluid service.
