HVAC Control Gear Oil 68 ISO 75W SAE
This synthetic gear oil carries an ISO Viscosity Grade of 68 and an SAE Grade of 75W for HVAC control systems. The NSF H1 food-grade rating and absence of additives make it suitable for equipment where incidental contact may occur. It operates between 0 and 180 degrees Fahrenheit with a pour point of 0 degrees Fahrenheit.
Replaces Lower-Grade Lubricants In Food-Grade
The jump is worth it when a system requires NSF H-1 compliance and a pour point at 0 degrees Fahrenheit without additives. Older mineral-based fluids without the same certification cannot meet the same safety standard in temperature-sensitive HVAC controls.
Limited By Bottle Volume And Single Viscosity Grade
The 16 oz container provides 33 lb of fluid, which restricts use to smaller reservoirs or top-off tasks. The fixed 68 ISO and 75W SAE ratings mean the oil cannot cover equipment that demands a different viscosity range or additive package.
