Chemlube® Heavy Duty EP Diester Gear Oils


Chemlube® EP Gear Oils consist of five SAE rated, fully 100% synthetic, heavy duty gear oils composed of synthetic ester base fluids for a wide variety of extreme pressure industrial applications and automotive differential applications. Areas of special interest are extreme environmental applications, as well as those where high heat resistance, anti-wear and superior lubricity of enclosed gearboxes is a necessity. The highly polar nature of these ester based gear oils allows them to wet metal surfaces and provide lubrication on start-up after prolonged periods of inactivity.
