Super Lube O-Ring Silicone Lubricant is a specially formulated non-curing silicone fluid that is designed for lubricating, sealing and conditioning O-rings and other regulator and valve system components. It is compatible with most plastics and rubbers. In addition, the product is waterproof, protects against moisture, oxidation and is heat stable. Using Super Lube O-Ring Silicone Lubricant during installation helps protect an O-ring from damage by abrasion, pinching or cutting. It also helps to seat the O-ring properly, speeding up assembly operations and improving automated assembly. Lubricating the O-ring with Super Lube O-Ring Silicone Lubricant in dynamic pneumatic applications will extend the equipment service life. Super Lube O-Ring Silicone Lubricant will help reduce the overall leak rate in vacuum applications by filling the spaces of the glands surfaces and lowering the permeation rates of the elastomer. Meets former USDA (H1) guidelines.
