Bonded seals for completion tools


JST offers a wide range of molded elastomer (rubber) products for exploration, drilling, and well-service applications.


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 elastomer-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 NBR, HNBR, FKM or Aflas to corrosion resistant metal and can provide seals for various temperature ranges and/or H2S applications. The metal frame like 20# steel, 8620, 4140 are commonly used.


JST can provide the best sealing types and materials for various oil and gas drilling and exploration applications, so as to maximize the service life and performance of the sealing system.
