Parker 475406 Polyolester Refrigeration Oil 68 Iso 5 Gal

Product Description

The PARKER 475406 is a polyolester (POE) refrigeration oil formulated to ISO viscosity grade 68 and SAE grade 10, supplied in a 5-gallon container weighing 44 pounds. POE oils are fully synthetic lubricants specifically engineered for use with HFC and HCFC refrigerants in refrigeration and air conditioning compressors. The 300 SUS viscosity rating provides the film strength needed to protect compressor bearings and moving surfaces under typical operating temperatures. Licensed HVAC-R technicians and refrigeration mechanics rely on this type of oil to maintain lubrication, reduce wear, and support system efficiency in modern sealed compressor systems.

This oil is suited for commercial and residential refrigeration systems, split-system air conditioners, heat pumps, and chiller applications where a synthetic POE lubricant is required. It is commonly used during compressor changeouts, refrigerant retrofits, or routine oil charges in systems operating on HFC refrigerants such as R-410A, R-404A, and R-134a. The 5-gallon container size supports shop use and field service operations where multiple charges may be required across several units.

Key Features

• Polyolester (POE) synthetic base oil compatible with HFC and HCFC refrigerant systems
• ISO viscosity grade 68, SAE grade 10 for broad compressor application coverage
• 300 SUS viscosity provides strong lubrication film under compressor load
• 5-gallon container supports high-volume shop and field service use
• Formulated to mix with and remain stable in the presence of modern refrigerants

Compatibility

Designed as an OEM-style refrigeration lubricant for hermetic and semi-hermetic compressors in systems requiring an ISO 68 polyolester oil. Consult the compressor manufacturer specifications to confirm the correct viscosity grade before charging.

Installation Notes

Refrigeration oil service should be performed by a certified HVAC-R technician following EPA Section 608 guidelines. Recover all refrigerant from the system before opening any refrigerant circuit. POE oil is highly hygroscopic and must be kept sealed until use to prevent moisture absorption. Use dedicated, clean equipment to transfer oil and avoid cross-contamination with mineral or alkylbenzene oils.
