Abstract: An isolation gasket for use between facing flanges of two flow conduit sections for fluid passage therethrough. The isolation gasket includes non-conductive layers and coatings that cover a flat metal core ring to provide electrical isolation, and a fire resistant layer adjacent another non-conductive layer wherein this side by side arrangement uniquely maintains a seal during a fire. In one form, a serrated ring portion of the flat metal core ring has a convex profile.

Abstract: A heel stock portion of an oil seal may be made of latex elastomer based compounds instead of volatile organic compounds. One embodiment of a latex elastomer based compound may comprise approximately 5-35% aramid fiber, approximately 10-20% metal oxide, approximately 10-60% carbon filler, approximately 1-5% curative, approximately 20-50% latex flouroelastomer, and approximately 10-50% mineral filler by weight based on the weight of the heel stock part of an oil seal. Another embodiment of a latex elastomer based compound may comprise approximately 10-40% aramid fiber, approximately 2-10% mineral fiber, approximately 2-10% carbon filler, approximately 20-40% mineral filler, approximately 2-10% metal oxide, approximately 5-20% glass fiber, approximately 1-5% curative accelerator, approximately 1-5% curative, approximately 1-5% anti-oxidant, approximately 10-40% latex nitrile elastomer, and approximately 1-5% polyester fiber by weight based on the weight of the heel stock part of an oil seal.
