Product Description

SAVE TIME BY EASILY DETERMINING IF THE A/C SYSTEM NEEDS TO BE FLUSHED

The condition of the refrigerant in your A/C system is an important factor in the proper operation of all components and overall cooling efficiency. The only way to actually see the condition of the refrigerant in your vehicle’s A/C system is with the use of the Mastercool visual inspection sight glass.

This unit can be used with a standard vacuum pump or with the vacuum function on your R/R/R machine. Easy to follow instructions will guide you through the use of either option.

• Allows user to visually inspect the refrigerant in any R134a or R1234yf system and identify excess dye, oil or debris
• Allows the user to extract a small portion of the refrigerant for actual visual inspection
• Leak free, ball valve controlled and will allow the refrigerant extracted for the visual inspection to be deposited back into the system
