ISO 68 Air Compressor Oils

Compressor oil grade 68 is used for lubrication in equipment and applications identified for ISO 68 viscosity. The supplied products support rotary screw and reciprocating air compressors, high-pressure gas compressors, industrial compressor maintenance, and moderately severe operating conditions. Some formulations are designed for food-grade applications, while others provide specific OEM-equivalent replacements. Confirm the required formulation and compressor compatibility before use.

The supplied ISO 68 products are used with rotary screw compressors, reciprocating compressors, and gas compressors. Product information also identifies piston and vane compressors within broader lubricant replacement ranges. Compatibility varies by formulation and OEM reference, so the compressor model, existing lubricant, operating conditions, and required specification should be checked against the relevant product or cross-reference guide.

The range includes mineral, partial-synthetic blend, full-synthetic, PAO, PAG, and synthetic diester formulations. Food-grade options meeting NSF H1 requirements are also listed for incidental food-contact applications. Product choices include general air compressor lubricants, gas compressor oils, OEM-equivalent replacements, and lubricants intended for industrial or moderately severe operating conditions.

Many products in this category are identified as 100% OEM compatible or as meeting or exceeding OEM specifications. Some are specifically positioned as replacements for named lubricant brands or compressor fluids. Compatibility should be confirmed using the product information, OEM requirements, and applicable cross-reference or compatibility guidance before pouring a replacement lubricant into operating equipment.

Yes. The supplied range includes full-synthetic ISO 68 compressor oils identified as NSF H1 or meeting H1 requirements for incidental food contact. These products are listed for food and beverage processing facilities and other applications requiring food-grade lubrication. NSF H1 status applies to the identified formulations, so the product label and technical documentation should be checked before use.

US Compressor provides technical support, lubricant selection guidance, customer contact support, and free oil analysis services across the supplied product range. Some products also include access to Safety Data Sheet and Technical Data Sheet documentation. Customers can provide their compressor type, current lubricant, OEM reference, and operating conditions to help identify a compatible ISO 68 option.
