The Mastercool Visual Inspection Sight Glass, No. 53376-YF, is designed to allow users to see the condition of the refrigerant in a vehicle's A/C system to determine whether it needs to be flushed. The unit can be used with a standard vacuum pump or with the vacuum function on a RRR machine. Instructions are easy to follow and helps guides users through the use of either option. The sight glass allows users to visually inspect the refrigerant in any R-134a or R-1234yf system and identify excess dye, oil, or debris. It also allows the user to extract a small portion of the refrigerant for actual visual inspection.
