NIBCO® PressACR Fittings

NIBCO’s PressACR® fittings are a joining method designed for use in copper tube systems for the creation, repair and maintenance of refrigeration and air conditioning applications. PressACR is approved for use with a wide range of refrigerants and lubricants and creates a safer installation as there is no flame or fire hazard with press technology.

NIBCO PressACR fittings are UL recognized to 700 PSI and feature a gray HNBR seal to help differentiate them from other NIBCO press products and to provide a permanent leak-proof connection.

PressACR fittings are approved for use with K, L and M hard copper tubing and soft copper tubing in 1/4" through 7/8" OD diameters. In sizes 1 1/8" and above, PressACR is only approved for use with K, L and M hard copper tubing. Straight and reducing couplings, 45- and 90-degree elbows, caps, Y-joints, and tees are available and are backed by the NIBCO 15-year warranty.

High-Quality Made in the U.S.

Engineered, designed and manufactured in the U.S. of the highest quality globally sourced pure copper, PressACR fittings feature NIBCO’s patent pending groove design and crimp pattern that supports the higher-pressure requirements of an HVACR system.

Meeting Stringent Certifications and Standards NIBCO PressACR fittings meet stringent certification and compliance standards including: ISO 5149-2, ISO 14903 helium leak test, ISO 14903 thermal cycle test, ISO 14903 fatigue test, ISO 14903 freeze test, ISO 14903 vacuum test, ASME B31.5, ASHRAE 15, ASTM G85 salt spray, and UL 109 vibration.

Faster, Safer Installations

PressACR brings the press joinery technology to refrigeration and air conditioning systems. The fittings allow user friendly, quick, flame-free installation that is safer for users when compared to soldering or brazing. Faster installation time means greater productivity at the job site and lower installed costs. Consistent joint quality means fewer callbacks and reliable performance.
