NIBCO INC. has launched 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 1/4-, 1/2-, 3/8-, 5/16-, 5/8-, 7/8-, and 1 1/8-inch sizes.
