Title: Multifunctional tool for automotive air conditioning system testing and maintenance

Abstract: An automotive tool for servicing air-conditioning (AC) systems equipped with quick-connect adaptors. May be used to service modern refrigerant R132A-compatible systems or retrofitted older systems. The tool is adapted for attaching, detaching, opening, and closing valved T-adaptors used to attach gas lines and pressure gauges such as required for adjusting pressure in AC systems at full operational pressure and temperature, and particularly finds use when the "hi-tap" and "lo-tap" fittings are in hard to reach places around the engine block or chassis. The tool includes swappable extension arms so that length and angular geometry may be adjusted as needed. The tool aids in avoiding injury on dangerously hot surfaces and moving fan blades or belts. Surprisingly, using two such tools, one for the high tap and one for the low tap, a mechanic may work each tool singlehandedly to complete any necessary pressure adjustments.
