Product Description
MOLYKOTE® L-1668FM Synthetic Blend Vacuum Pump Oil is an ISO VG 68 lubricant formulated specifically for oil-lubricated rotary vane vacuum pumps. Its synthetic-blend base combines mineral oil and polyalphaolefin technology with rust-, oxidation-, and corrosion-inhibiting additives. The amber oil is designed to maintain suitable viscosity and lubricating-film thickness at normal operating temperatures while supporting demanding service involving moisture, water, chemicals, or corrosive environments. It is NSF H1 certified for incidental food-contact applications and is used in industries including food packaging, medical sterilization, chemical manufacturing, and battery production.
