## Mineral reciprocating compressor oil, ISO 100

COM-100 is an air compressor oil for reciprocating compressors. Its mineral base and ISO 100 viscosity grade identify the product described in this listing.

For maintenance and purchasing teams, the full catalog number matters. Check your equipment's lubricant requirements before choosing an oil; a viscosity grade alone does not establish suitability for every compressor.

## A catalog-stated 4,000-hour service rating

The catalog describes this oil as Reciprocating Compressor Oil, Mineral, 4,000 Hour. COM-100 carries that stated 4,000-hour rating.

Follow your equipment documentation and maintenance guidance when planning service. The catalog rating should not be treated as a guaranteed oil-change interval for every machine or operating condition.

## Quality lubricants blended in the USA since 1949

Lubri-Loy has blended lubricants in the USA since 1949, with product quality central to the Lubri-Loy name.

Buying directly connects your team with the company behind the oil. Keep COM-100, ISO 100 and the 55 gal drum size together in your inquiry so the requested product is clear.
