Parker 475328 Suniso Mineral Compressor Oil 1 Gal Iso 32

Product Description

The PARKER 475328 is a virgin mineral refrigerant lubricant oil sold in a 1-gallon bottle, formulated for use in refrigeration compressors. Rated at 150 SUS viscosity and meeting ISO 32 grade, this Suniso-type oil is engineered for stable performance in refrigerant contact environments. Its high dielectric strength allows the oil-refrigerant mixture to act as an insulator between motor windings and the compressor body. High chemical stability limits reaction with refrigerants and other system components. A low pour point prevents the oil from congealing in refrigerant lines, maintaining flow through the system under low-temperature operating conditions. Licensed HVAC and refrigeration technicians install this product during compressor service or system commissioning.

This oil is intended for refrigeration compressor lubrication in systems where a mineral-based ISO 32 lubricant is specified. Typical applications include commercial and light commercial refrigeration equipment where the OEM compressor manufacturer calls for a virgin mineral oil of 150 SUS viscosity. It is suited for use in systems operating with compatible refrigerants that allow mineral oil circulation. Technicians should verify refrigerant and compressor OEM specifications before selecting this lubricant for any application.

Key Features

• Virgin mineral oil formulation rated at 150 SUS viscosity and ISO 32 grade
• High dielectric strength allows oil-refrigerant mixture to insulate motor windings inside the compressor
• High chemical stability minimizes reaction with refrigerants and system materials
• Low pour point prevents oil from congealing in refrigerant lines under low-temperature conditions
• Packaged in a 1-gallon bottle for controlled dispensing during service

Compatibility

Designed for refrigeration compressor lubrication in systems that specify a virgin mineral oil at ISO 32 grade and 150 SUS viscosity. Verify compatibility with the compressor manufacturer and refrigerant type before use.

Installation Notes

This lubricant is installed by licensed HVAC or refrigeration technicians during compressor replacement, rebuild, or scheduled oil service. Recover and reclaim all refrigerant before opening the system, following EPA Section 608 requirements. Use clean, dedicated equipment to avoid contaminating the oil charge with moisture or debris. Confirm the required oil charge volume and viscosity grade in the compressor manufacturer documentation before adding oil to the system.
