PCT No. PCT/US91/02830 Sec. 371 Date Mar. 2, 1992 Sec. 102(e) Date Mar. 2, 1992 PCT Filed Apr. 26, 1991 PCT Pub. No. WO92/19892 PCT Pub. Date Nov. 12, 1992.A head gasket assembly (18) is used for sealing a joint between a cylinder block (12) and a cylinder head (14). At least portions of the head gasket assembly (18) must withstand high temperatures, high pressures and be flexible for sealing fluid passages such as lubricating oil and cooling water mixtures. The present head gasket assembly (18) is comprised of a main gasket body (40) constructed of a sealing material (46) having a plurality of apertures (48,50,52) positioned therein. A portion of the plurality of apertures (48,50,52) includes a combustion opening (52) having a first ring (54) positioned in the periphery of the combustion opening (52). A plurality of tape strips (60) having an end portion (62) attached to a side of the sealing material (46), partially surrounding the fire ring (54) and another end portion (64) attached to the other side of the sealing material (46). Thus, the flexible main gasket body (40) and the rigid fire rings (54 ) are fixedly attached together and provide a head gasket assembly (18) which has very good handleability, sealability and functional characteristics.
