Even though the circulated refrigerant is the working fluid required for cooling, lubricant or oil is needed for lubrication of the compressor’s moving mechanical parts.

For HVAC contractors to be optimally productive on the job, stopping the accelerated corrosion of metal components and facilitating maintenance is essential.

This line of polyolester (POE) lubricants is specifically designed for air conditioning and refrigeration compressors. These lubricants are formulated from high quality materials, using a customized manufacturing process.

Under normal conditions, there will always be a small amount of oil that escapes a compressor’s crankcase and is circulated with the refrigerant throughout the system. It is for this reason that refrigerant oil and the refrigerant itself must be soluble in one another. It is the velocity of the circulated refrigerant that carries the oil back to the compressor’s crankcase. If the two were not soluble in one another, this phenomenon could not happen.

The WD-40 Specialist Grease line includes Superior Performance True Multi-Purpose Grease, Heavy-Duty High Temperature Grease, Heavy-Duty Extreme Pressure Grease, and Marine-Grade Water Resistant Grease. The products are interchangeable with each other, meaning they won’t cause cross-contamination issues that compromise performance or effectiveness.
