Shop vacuum pump oil, synthetic fluids, flushing fluid, PFPE fluids, diffusion pump fluids, and OEM-equivalent replacement oils.
The right vacuum pump oil helps protect vanes, seals, bearings, and internal pump components while improving pump performance and service life. Vacuum Pump Supply offers mineral vacuum pump oil, synthetic vacuum pump oil, flushing fluid, diffusion pump fluids, and specialty lubricants for many major vacuum pump brands.
Use this page to quickly find oil by type, application, or OEM cross-reference.
General-purpose vacuum pump oil for many rotary vane and oil-sealed vacuum pumps.
Synthetic fluids for applications requiring improved thermal stability, longer service life, or higher performance than standard mineral oil.
Use flushing fluid during maintenance to help remove degraded oil, residue, and contamination before refilling with fresh vacuum pump oil.
Specialty fluids for chemically demanding or oxygen-service applications where standard mineral or synthetic oils are not suitable.
Diffusion pump fluids for high-vacuum systems, lab equipment, coating systems, and other diffusion pump applications.
Find OEM-equivalent vacuum pump oil replacements by brand, oil family, or viscosity.
| Oil Type | Best For | Notes |
|---|---|---|
| Mineral Oil | General rotary vane pump service | Most common choice |
| Synthetic Oil | Higher heat, longer service, demanding use | Better stability |
| PFPE Fluid | Chemical / oxygen-compatible applications | Specialty use only |
| Diffusion Pump Fluid | High-vacuum diffusion pumps | Not for rotary vane pumps |
| Flushing Fluid | Cleaning during oil changes or rebuilds | Use before fresh oil |
