Enviro-Safe Pittstop R12 R22 Oil Checker Analyzer Tester 10 pack #5025 Description Pittstop R12/22 Oil Checker 10 Pack Part#: 5025 Note: This item will not work on R134 systems. If you need to check the oil for an R134 system, please purchase the R134 oil checkers. A cost effective and easy way to detect air conditioning oil levels and harmful acids in the oil of A/C systems without changing out the A/C system and draining all the oil from the system. Many A/C compressor failures are caused by low oil levels and dirty contaminated oil in the A/C system. The use of this low cost oil checker can save you the cost of a new compressor plus the down time caused by the replacement of a compressor. Automotive and commercial installers can use existing service fittings to utilize the oil checker. Also available in 2 packs. Available for R134a as well.
