Corning 1395-OR Silicone O-Ring for Laboratory Bottle and Tube Closures

The Corning 1395-OR Silicone O-Ring is a replacement sealing component designed for compatible Corning/PYREX laboratory glassware closure systems. The silicone O-ring is used with compatible screw-cap assemblies to help create a leak-resistant seal between the closure and laboratory vessel. Corning specifically documents the 1395-OR as a replacement part for its PYREX graduated hybridization tubes, which use a GL45 orange plug-seal cap incorporating a silicone O-ring. It is useful for replacing an O-ring that has become worn, damaged, misplaced or otherwise unsuitable for continued use without replacing the complete laboratory vessel.
