Pro-source 2556511263PRO Push-to-connect Tube Fitting 3-pack

Product Description

The PRO-SOURCE 2556511263PRO is a push-to-connect tube-to-tube fitting designed for fast, tool-free connections in compressed air and water systems. Constructed from nickel-plated brass, it handles working pressures up to 250 psi and operating temperatures from 0 to 160 degrees F. The push-to-connect design allows a technician to insert tubing and achieve a secure, leak-resistant seal without threading or soldering. This fitting is sold as a 3-pack, making it practical for service calls where multiple connection points are involved. Plumbers, HVAC technicians, and industrial maintenance personnel routinely install this type of fitting in both new construction and retrofit applications.

This fitting is suited for residential and light commercial plumbing and pneumatic systems where tubing outside diameter measures 12.00 mm. It is rated for use with compressed air and water lines, making it versatile across HVAC refrigerant-side ancillary lines, pneumatic controls, and potable or process water distribution. The Buna O-ring provides a reliable internal seal across its full operating temperature range. The 3-pack quantity supports multi-point installations or stocking for routine service work.

Installation Notes

Shut off and depressurize the system completely before removing or installing any fittings. Cut tubing cleanly and squarely with a proper tube cutter to ensure full engagement and a leak-free seal. Verify the tubing outside diameter matches the fitting spec before insertion. Plumbers and HVAC technicians should confirm that the installed system pressure and temperature remain within the rated limits of this fitting during operation.
