SYF-1155 SILICONE DIFFUSION PUMP OIL
Product Description
Silicone diffusion pump fluid is a methyl phenyl silicone based diffusion pump fluid. The product has been formulated with an advanced technology additive system for superior performance. It shows excellent resistance to oxidation, wear, rust and corrosion. Silicone Diffusion Pump Fluid does not degrade when exposed to heat or intake gas. These are clear, colorless; fluorinated synthetic oils that are nonreactive, nonflammable, and safe in chemical and oxygen service, and are long-lasting.
