Krytox VPF1525 Oil | For High Vacuum Applications

NSF H-1 Certified For Incidental Food Contact

Krytox VPF 1525 vacuum pump fluids are used in applications where conventional vacuum pump oils cause safety, waste disposal, and maintenance problems. They are nonflammable and eliminate the chance of fire in pumps. They are nonreactive and safe to use in oxygen systems. They can replace competitive PFPE fluids as well as any other type of vacuum fluid. Krytox? fluids do not contain acetal groups, which are susceptible to attack by Lewis acids. This gives Krytox? superior stability as a vacuum pump fluid. Krytox vacuum fluids are precisely distilled to provide low vapor pressures and superior performance. In addition, Krytox fluids are recyclable.

Why Krytox VPF 1525 Oil?

While Krytox VPF fluids are inert and non-reactive to all elastomers, plastics, and metals, the soluble additives in Krytox? XP products have not been tested with all materials. Initial testing has shown no problems with Teflon? fluoroplastic resin, Kalrez? perfluoroelastomer parts, Viton? fluoroelastomer, nitrile, and silicone rubbers. The performance of the soluble additives could degrade at temperatures more than 182 °C (360 °F) over a long period of time.?
