RLS’ aluminum press fittings are a single-component, press-to-connect system engineered for high-pressure aluminum refrigeration joints. Using the press tool and jaws, a typical connection can be made in less than 25 seconds, without the need for an open flame, flammable gas or any heat source. In addition, there is no special tube preparation or sealant required. The tube is prepared just as it is for brazing and then the one-piece fitting is pressed into place. The refrigeration press fittings are UL-listed to 700 psi operating pressure and are approved for use with a wide range of common refrigerants.
