    Vacuum Pump Oil, Fluids & Lubricants

    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.

    Maintenance tip:
    Always replace vacuum pump oil after a rebuild, after contamination, or when oil appears dark, milky, dirty, or degraded. Fresh oil is one of the easiest ways to protect your pump investment.
    Need an OEM equivalent?
    We can help match vacuum pump oil for Leybold, Edwards, Busch, Becker, Welch, Alcatel / Adixen / Pfeiffer, Rietschle, and other major brands.

    Choosing the Right Vacuum Pump Oil

    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
