The Hecat FAD-100 Universal A/C Adapter Kit can be used with many types of A/C flushing equipment, and can also be used to isolate components for pressure or vacuum testing. Multiple slotted support plates support various-sized tube ends and line nuts. The chamfered area on the support plates align flared ends to sit level and prevent damage. Cone seating is done by hand, and a set of rubber cones is included. The clamp screw terminates with 1/4 male refrigerant flare to allow for universal use, and the internal flow path is 0.250".
