Oil seals & Gaskets are mechanical seals which fill the space between two or more mating surfaces, generally to prevent leakage from or into the joined objects while under compression.
Oil seals & Gaskets allow "less-than-perfect" mating surfaces on machine parts where they can fill irregularities. It is usually desirable that the gasket be made from a material that is to some degree yielding, such that it is able to deform and tightly fill the space it is designed for, including any slight irregularities. A few gaskets require an application of sealant directly to the gasket surface to function properly. YAMAHA genuine parts stock a wide range of quality gaskets & oil seals made especially from eco-friendly materials.
