PFPE grease

PFPE Grease

Starting at $29.5

Due to the harsh environments diffusion pumps operate, specialized grease is required for air-tight, optimal vacuum performance. Our PFPE grease thickened with PTFE is the ideal solution due to its ability to withstand high temperatures at very low evaporation loss.

Choosing Diffusion Pump Oil

When it comes to diffusion pump oil, Enparticles offers one of the highest performing formulas in the market today. As the use of hydrocarbon based pump oils are becoming less common, silicone diffusion pump fluid has become the ideal solution due to its low vapor pressure, excellent resistance to oxidation and radiation, chemical and thermal stability, and more importantly, a long life cycle before requiring an oil change. Due to these properties, our ECO-702, ECO-704 and ECO-705 silicone diffusion pump oil is able to withstand and maintain ultimate vacuums of 10E-5 Torr up to 10E-10 Torr (untrapped) without much maintenance, just the occasional topping off when oil levels decrease.

For vacuum applications in most severe operating environments including strong acids, oxygen, combustible or corrosive compounds, and even ionizing radiation, our PFPE diffusion pump oils is your ideal solution. As with all PFPE oils, our ECO-18/8 and ECO-25/9 PFPE diffusion pump oils are completely inert and does not have a flash or fire point making this one of the safest oils to use in extreme vacuum pumping environments. Our PFPE oils can maintain an ultimate vacuum of 10E-8 to 10E-9 Torr based on model.
