Pro-source 2555611863PRO Push-to-connect Tube Fitting

Product Description

The PRO-SOURCE 2555611863PRO is a push-to-connect tube-to-universal-thread tube fitting designed for fast, tool-free connections in compressed air and water systems. Constructed from nickel-plated brass, this fitting accepts a 12 mm outside diameter tube and is rated to 250 psi. The universal thread design accommodates a wide range of mating ports, making it a practical choice for field installations where thread standardization varies. Licensed plumbers, HVAC technicians, and mechanical contractors install this type of fitting in both new construction and service work.

This fitting is suited for residential and light commercial compressed air distribution lines and potable or process water plumbing. The push-to-connect mechanism allows quick tube insertion without ferrules, nuts, or thread sealant on the tube side, reducing installation time in tight spaces or high-volume service calls. Each package contains 3 fittings, supporting multi-point installations from a single order.

Compatibility

Designed for use with compressed air and water systems requiring a 12 mm outside diameter tube connection to a universal threaded port. Suitable for pneumatic and fluid distribution lines in residential and light commercial applications.

Installation Notes

This fitting is typically installed by licensed plumbers, pipefitters, or HVAC mechanics. Depressurize and drain the line fully before removing or installing any push-to-connect fitting. Ensure the tube end is cut cleanly and squarely with no burrs before insertion to maintain a proper Buna-N O-ring seal. Verify thread compatibility on the mating port before tightening; do not overtighten the threaded side into softer port materials.
