gasket is a mechanical seal that fills the space between two or more mating surfaces, usually to prevent leakage from or within the joined objects while under compression. Ring gaskets are used with plumbing fittings to create airtight seals in plumbing repair, maintenance, or installation work. Leaf gaskets are used to create custom gaskets. Cam and groove gaskets provide a tight seal between couplings in low-pressure fluid applications such as regulators and pumps. Sanitary gaskets are used in piping systems for the food and beverage industry. Specifications: Height: 0.25 in. Width: 7 in. Length: 5.25 in.
