About Refrigeration Lubricants
Adding lubricant to HVAC or automobile systems helps maintain their efficiency. Estercool oil is a refrigeration lubricant that helps prevent corrosion and acid from forming within systems. Designed for use with R12 or R134a AC systems, this refrigerant oil can replace mineral or paraffin oils. We also have hand operated oil pumps that are compatible with alkyl-benzene, ester-based, POE oil, mineral and synthetic oils. When changing these oils, keep in mind that we have drip pans in our AC and refrigeration accessories section for assistance. Our refrigerant pressure regulators also manage proper refrigerant levels.
