Pittstop R134A Oil Checker
Finally, a product offering customers a cost effective and easy way to detect air conditioning oil levels and harmful acids in the oil a/c system without removing complete A/C system and draining of all oil from 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 down time caused by the replacement of a compressor.
Automotive and commercial installers can use existing service fittings to utilize the Pittstop Oil Checker.
Oil Checkers are available in 2 and 10 packs.
Also available for R12.
- Operate the A/C unit for 15-20 minutes.
- Put the oil checker between your thumb, index finger and middle finger and with the A/C compressor running, push down on the low pressure (suction line)(this is normally the big A/C line) 2 or 3 times.
- Set the checker tube upright for 3-5 minutes then pick up the checker and check the oil level.
- If the tube is 1/2 or more full, DO NOT add oil to the system. If the checker is below 1/2 full, add oil to your system.
Note: The compressor clutch must be engaged or running to get the correct reading.
