A gasket is a mechanical seal which fills the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression. Ring gaskets are used with plumbing fixtures to create tight seals in plumbing repair, maintenance, or installation jobs. Sheet gaskets are used to create custom gaskets. Camandgroove gaskets provide a tight seal between couplings in lowpressure fluid applications such as regulators and pumps. Sanitary gaskets are used in piping systems for the food and beverage industry. Features. Left Side Single 3Sided Door Gasket. Made with high quality materialSpecifications. Size 36 x 76.
