Pro-source 2555905565PRO Push-to-connect Tube Fitting 5pk

Product Description

The PRO-SOURCE 2555905565PRO 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 corrosion resistance and reliable sealing up to 250 psi. The fitting accepts tubing by outside diameter and uses a Buna-N O-ring for a secure, leak-resistant seal. This type of fitting is commonly installed by plumbers, HVAC technicians, and maintenance professionals who need repeatable, removable connections without threaded fittings or ferrule compression tools. Each package contains 5 fittings.

This fitting is suited for residential and light commercial applications involving compressed air lines and potable or non-potable water distribution. The push-to-connect design makes it a practical choice for pneumatic control tubing, equipment supply lines, and retrofit or repair work where tubing needs to be connected and occasionally disconnected. The 5 mm outside diameter tube compatibility targets smaller-bore tubing runs common in instrumentation, HVAC controls, and compressed air distribution panels.

Designed for use with compressed air and water systems using tubing with a 5 mm outside diameter. Suitable as an OEM-style or replacement push-to-connect tube fitting in pneumatic and fluid distribution applications.

Installation Notes

Depressurize and isolate the line completely before installing or removing push-to-connect fittings. Ensure tubing ends are cut cleanly and squarely with no burrs, as ragged cuts can damage the O-ring seal and cause leaks. A licensed plumber or qualified HVAC technician should verify that the fitting pressure rating is appropriate for the system operating conditions. Follow applicable codes including ASME B31.1 or local plumbing codes as required for the installation type.
