HVAC Gear Oil – ISO 68, SAE 80W

This synthetic gear oil carries ISO viscosity grade 68 and SAE grade 80W for gear, bearing and circulating systems. The yellow fluid meets U. S. Steel 224, AGMA 9005 and DIN 51517 Parts 1, 2, 4. It operates from minus 15 to 195 degrees Fahrenheit with a viscosity index of 119.

Verify system requirements before ordering

Confirm that your equipment specifies ISO 68 viscosity and SAE 80W grade for the intended gear or circulating application. Check that the operating temperature range of minus 15 to 195 degrees Fahrenheit matches the service environment. Ensure the OEM approves lubricants meeting U. S. Steel 224, AGMA 9005 and DIN 51517 standards.

Synthetic base with no additives

The synthetic base oil contains no additives and delivers a flash point of 450 degrees Fahrenheit and a pour point of minus 49 degrees Fahrenheit. Supplied in a yellow 25‑pound bottle, it is suited for gear, bearing and circulating systems where the listed standards apply. Buyers needing NSF‑rated lubricants or specific Timken OK Load values should select a different product.

Questions about this item

What comes in the jug and is any extra hardware needed?

The 1-gallon jug contains 25 lb of yellow synthetic gear oil rated ISO 68 and SAE 80W; no additional hardware or additives are required.

How do I choose between the ISO 68 and SAE 80W ratings on the same jug?

Both ratings describe the same fluid — ISO 68 for industrial specs and SAE 80W for automotive specs — so one jug satisfies either requirement.

What does the 119 viscosity index mean when the oil is running in a gearbox?

A viscosity index of 119 indicates the oil resists thinning at the 195 °F maximum operating temperature and stays pumpable down to the -15 °F minimum.
