The bonded seal is used in work-over and sand control operations. With the bonding of elastomer to a steel core, this serve to prevent excessive rubber compression under loading.

JST manufactures a complete size-range of rubber-to-metal bonded seals. We use an exclusive two-phase manufacturing process to produce highly-reliable bonded seals capable of controlling either conventional wellbore fluids or exotic media. By using bonding processes, we overcame the problems customarily associated with bonding Viton® and Aflas® to corrosion resistant metal and can provide seals for high temperature and/or H2S applications.
