Pro-source 2555806665PRO Push-to-connect Tube Fitting 5-pack

Product Description

The PRO-SOURCE 2555806665PRO 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, this fitting delivers a rated working pressure of 250 psi and uses a Buna-N O-ring for a reliable, leak-resistant seal. The push-to-connect design allows a technician to insert tubing and achieve an immediate, secure connection without ferrules, nuts, or wrenches. Each package contains 5 fittings, making it practical for service calls and bench stock. This fitting suits plumbers, pipefitters, HVAC technicians, and industrial maintenance professionals working with small-diameter tubing runs.

This fitting is sized for 6 mm outside diameter tubing and is rated for use with compressed air and water service. It is well suited to light commercial and industrial pneumatic lines, fluid transfer systems, and HVAC condensate or instrument air applications where quick-disconnect capability and compact form factor are priorities. The tube-to-tube configuration makes it appropriate for inline connections and repairs within existing tubing runs.

Installation Notes

Installation is performed by plumbers, pipefitters, or HVAC technicians. Before installing or removing the fitting, depressurize and isolate the line completely. To release tubing, depress the collet ring while pulling the tube free — do not force or pry the connection. Verify tubing outside diameter and confirm compatibility with the fluid media before placing the fitting in service.
