The Kurt J Lesker Company® exclusively distributes and stocks Fomblin® (PFPE) inert fluids for diffusion and mechanical vacuum pumps, silicone fluids for diffusion pump, and Santovac® for the lowest ultimate vacuums using diffusion pumps. We supply the popular Apiezon® hydrocarbon greases and vacuum lubricant and, in addition, Dow Corning 976 Silicone and Klüber inert greases. For vacuum sealing, we offer epoxy-based and silicone-based materials. We are also the exclusive distributor of Galden® heat transfer fluids for closed loop chiller systems.
The Kurt J Lesker Company® is dedicated to providing our customers with quality products and services to enhance and protect their process. For over 30 years, the Kurt J. Lesker Company has been recycling Fomblin® and Krytox® inert PFPE and silicone fluids. Our vacuum oil recycling service provides a significant savings over the cost of new fluid and helps protect our environment by drastically reducing the amount of waste contributed to the waste stream.
For almost 40 years we have manufactured hydrocarbon vacuum pump fluids of all grades and viscosities. Our KJLSS semi-synthetic hydrocarbon vacuum pump oil offers superior chemical stability. KJLC®'s new line of semi-synthetic mechanical pump oils offers superior performance. KJLSS Oil contains an anti-oxidation additive which extends the useful life of the oil. With its low vapor pressure this oil is an ideal choice for a variety of applications. KJLSS is a semi-synthetic oil with a high viscosity index, which makes it much more energy efficient than many other vacuum pump oils. It has the added benefit of being able to withstand higher operating temperatures. This new oil is available in four different types, with varying viscosities.
All fluids, vacuum greases, and sealants can be purchased online.
