Whether it is on onshore oil wells, offshore drilling platforms, or subsea oil wells, it is necessary to avoid blowouts at all costs - or uncontrolled release of natural gas and/or crude oil from excavation sites. JST provides high-quality industrial rubber products for the oil field industry, such as rubber blowout preventer seals.

With the help of the blowout preventer seal, the well can be safely sealed when needed. Safety is the primary task for anyone working on a drilling platform, which is why it is necessary to choose high-quality blowout preventer seals.

JST produces outer bop seal and inner bop seal, also known as BOP seals. We usually use material HNBR70/HNBR85/HNBR90+42 Cr. Our material meets with NORSORK-M710 and it is suitable for H2S working medium.

Our special proprietory manufacturing process ensures that the rubber and metal plates remain bonded to each other even under the most severe applications. In BOP, inner seal and outer seal are used together.
