A/C compressor ester lubricant 32 oz

Supercool E31 is a yellow-tinted ester oil formulated for automotive air-conditioning compressors. It comes in a 32 oz plastic bottle and includes an O-ring conditioner to help maintain seal elasticity during service.

Fits R-12 and R-134a systems with mineral oil or PAG

The lubricant is compatible with both R-12 and R-134a refrigerant circuits and works alongside mineral oil or PAG lubricants already present. Its synthetic base frees technicians from matching a specific PAG viscosity grade while still protecting compressor internals.

High flash point and boiling point for sustained

With a flash point of 440 Degrees F and a boiling point of 1,058 Degrees F the fluid resists thermal breakdown during extended compressor cycling. A viscosity index of 100 indicates stable film strength across the temperature range encountered in continuous duty.

Questions about this item

Will the 100 viscosity index hold up during extended compressor runs?

The ester oil carries a viscosity index of 100 and a boiling point of 1,058 Degrees F, so it resists thinning even under sustained high-temperature operation.

How hot does the fluid get and does it create fumes during all-day use?

Flash point is 440 Degrees F and boiling point is 1,058 Degrees F, so normal A/C pressures keep it well below vapour or ignition risk during continuous duty.

Which refrigerants and oils must already be in the system for this lubricant to be compatible?

It is formulated for R-12 and R-134a systems and mixes with mineral oil and PAG lubricants, plus it includes an O-ring conditioner for existing seals.
