About Us

Welcome to Enparticles Diffusion Pump Oil, the leading manufacturer and distributor of high quality diffusion pump oils in the United States and all over the world. We readily stock large quantities of ECO-702, ECO-704, and ECO-705 silicone diffusion pump oil to ensure our customers are always taken care of in a timely manner when they need to top-off or replace their diffusion pumps with premium grade oils.


Enparticles started offering diffusion pump oil in 2013 when Dow Corning decided to remove DC-702, DC-704, and DC-705 from their products lists. At the time, many manufacturers that use diffusion pumps in production processes were unable to locate a trustworthy source for replacing Dow Corning’s premium grade oils. Enparticles has stepped up to the challenge and currently offers the best drop-in alternative. Having more than two decades of experience with silicone recycling and oil production, the founders of Enparticles Diffusion Pump Oil with the help of several elite silicone chemical engineers decided to create a line of specialty silicone diffusion pump oil that match and even exceed the performance of the discontinued oils. Since then, Enparticles diffusion pump oil currently sets the industry standard for diffusion pump oil and is one of the most trusted name in the market.

5. Reclamation of Used Diffusion Pump Oil As diffusion pumps need to be drained and completely refilled on a routine schedule, there is a lot of used diffusion pump oil in the market today that maybe headed for landfills. At Enparticles, we strongly believe in recycling. The silicone diffusion pump oil we collect are filtered and reclaimed into silicone oil that can be reused in other, lower-level applications. Please note that reclaimed silicone oil from diffusion pumps are never placed into our ECO line of products.
