MOC® A/C Quiet™ (#01331) is a highly effective ester-based oil lubricant for automotive air-conditioning systems. This lubricant performs four key functions:
- It lubricates the entire air-conditioner system, including the compressor.
- It helps prevent acid from forming and inhibits corrosion.
- It encapsulates moisture and keeps it from damaging internal parts.
- It contains a special color dye for leak detection (under black light).
Note: A/C Quiet™ should be added to a system after an A/C service, to quiet a noisy compressor, if refrigerant/oil level is low, as a preventative maintenance step and to detect system leaks.
