It is sold as a package of five gaskets, giving you enough on hand for a full rebuild or for keeping spares for future service work. The gasket is made from a glass material formed into a round shape designed to seat properly against the mating crankcase and cylinder block surfaces, helping maintain a proper seal and prevent leaks between these two components.\u003c\/p\u003e\u003cp\u003eEach Sierra 18-2512-9 gasket is built to meet or exceed the quality of the original equipment part it replaces, making it a reliable choice for engine maintenance and rebuild jobs.
