Gaskets help seal surfaces and prevent leaks. 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. 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, dairy, beverage, pharmaceutical, and biotech industries.
