Inland 19 ULTRA® Semi-Synthetic Vacuum Pump Oil

Disclaimer: Spigots/Faucets are only compatible with 5 Gallon Jugs and must be purchased separately

Inland ULTRA® products are semi-synthetic hydrocarbon fluids designed to endure thermal and chemical stresses much better than standard vacuum pump fluids. The ultra-refined process eliminates nitrogen, sulfur, oxygen, and aromatic hydrocarbons, leaving a clear base stock virtually free of impurities.

The additive package will not volatize under thermal stress; the antioxidant will stay in solution and bond up to four times as many radicals as other antioxidants, extending the life of the pump and the fluid.
