A/C Compressor Ester Lubricant 8 oz

Supercool E7 is an ester-based lubricant formulated for automotive air-conditioning compressors. The fluid comes in an 8 oz plastic bottle and has a yellow tint with a bright, clear appearance. It is compatible with R134a, R12 and R22 refrigerant systems.

Technicians servicing R134a, R12 or R22 systems

This lubricant suits workshops and mobile technicians who need an ester fluid approved for those three refrigerants. Buyers who require a product with a stated dilution ratio or a specified viscosity at 100 °F should look at alternatives that publish those figures.

Boiling point above 1058 °F

The lubricant shows a boiling point greater than 1058 °F and a flash point greater than 440 °F, indicating high thermal stability under compressor operating temperatures. These two figures are the primary specifications that confirm the fluid will resist breakdown in high-heat A/C applications.

Questions about this item

Does the 8 oz plastic bottle fit the standard A/C service port on my R134a system?

The bottle is a standard 8 oz plastic container with a pour spout; it connects to the low-side service port using a common refrigerant charging hose and adapter, not directly to the port.

What is the correct way to add this ester lubricant during an A/C recharge?

Add the lubricant through the low-side charging port while the compressor is running, after vacuum evacuation but before refrigerant; the common mistake is pouring it into the high-side port or with the engine off.

How often should this ester lubricant be replaced in an R12 or R134a system?

Ester lubricant does not require scheduled replacement; it remains in the system for the life of the compressor unless a major repair opens the circuit or contamination occurs.
