The gasket material should have good flexibility, low density, and high tensile strength. It should also have a resistance to chemicals and internal pressure, and durability. It must also have excellent adhesion properties with itself and anything it touches. The ideal gasket will not only seal but also protect against corrosion. Further abrasion, vibration, impact, and temperature extremes need consideration. http://www.autopartsxdl.com/honda-gasket/
