Bonded seal, also known as BS connection seal, hydraulic seal ring, or washer, is a steel ring with a vulcanized elastomer lip (NBR, HNBR, FKM, or EPDM). The Bonded seal ring provides an effective sealing solution for: under pressure, vibration, in rather extreme temperature use. Techné's Bonded seal conform to ISO 4042 for coating. Applications of Bonded seal rings are diverse: they can be used for sealing fittings, screws, or threaded plugs. Due to their robust structure, Bonded seals can also replace copper gaskets as they can withstand higher pressures. Bonded seals can be used in other assemblies subjected to high pressures which require perfect sealing. Materials The Bonded seal consists of two parts: an outer metal part and an inner elastomer lip. The metal part of a Bonded seal is chosen based on the pressure and oxidation attacks it will endure. Tensile tests are conducted to characterize its pressure resistance. Techné provides the metal part in the following steels: DC01-270 steel with Zn coating DC01-590 steel with ZnNi coating AISI 304 stainless steel with Zn coating AISI 216 stainless steel with ZnNi coating AISI 316 L stainless steel with passivation Other steel grades available upon request Depending on the fluid to be sealed, the pressure to be withstood, and the environment the Bonded seal is aimed at, Techné offers different elastomer materials: NBR 80±5 IRHD HNBR 80±5 IRHD FKM 80±5 IRHD EPDM 80±5 IRHD Upon request, other hardness options can be provided: 70, 85, and 90 IRHD.
