HVAC Control 680 ISO 140W SAE

This synthetic gear oil carries an ISO Viscosity Grade of 680 and an SAE Grade of 140W. It is formulated for enclosed gearboxes, heavy-duty chains, bearings, blowers, slideways and guide posts. The fluid suits maintenance teams that need a single high-viscosity lubricant for demanding industrial drivetrains.

Amber synthetic base with no additives

The amber-coloured fluid uses a synthetic base oil and contains no additives. A viscosity index of 207 indicates stable thickness across temperature swings. The 25 lb bottle provides a practical fill volume for reservoir top-ups and scheduled change intervals on supported equipment.

Operating window from 10 to 200 Degrees F

The lubricant remains pumpable down to a pour point of -20 Degrees F and is rated for continuous use up to 200 Degrees F. A flash point of 480 Degrees F adds a high-temperature safety margin. Systems that require lower viscosity grades or specific additive packages will need a different product.
