NIBCO PressACR™ Fittings Improves Installation Method for HVACR Applications


NIBCO INC. launches PressACR™ fittings, a joining method designed for use in copper tube systems for air conditioning and refrigeration 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 (Hydrogenated Nitrile Butadiene Rubber) seal to help differentiate them from other NIBCO press products. Straight and reducing couplings, 45 and 90 degree elbows, caps, Y-joints, and tees are available in sizes ¼”, ½”, 3/8”, 5/16”, 5/8”, 7/8”, and 1-1/8”.

Made in Stuarts Draft, Va., with the highest quality of globally sourced pure copper, PressACR fittings feature our patent pending groove design and are specifically engineered to install with the NIBCO PressACR 19kn tool which creates a round crimp pattern that supports the higher pressure requirements of HVACR systems.

NIBCO PressACR 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.
