Downhole MWD centralizer rubber fins

Bidirectional high-pressure ball valve seat seal is a type of seat sealing that can withstand bidirectional pressure, with good low-temperature performance and airtightness, and is widely used in 6D ball valves.

JST's metal end cap seal is elastomer bonded onto 2 steel caps. This provides high level of extrusion resistance.

Spring energized valve stem packing contributes to the overall performance of industrial operations. They serve the vital task of keeping oil and liquids in while keeping contaminants out.

A seal assembly for use in a wellbore tool, it acts as a flow restrictor protecting a lower end of the seal assembly from high pressure and/or high volume flow.

JST ESY series design is commonly used as dynamic seal for ball valve stem, and the ESY with various V rings and T shape support rings could be used for fugitive emission valves, meeting the requirements of ISO-15848.

Rod seals are static seals installed in glands or housings to prevent the leakage of fluid from within a cylinder to the outside as the rod cycles.

We have been manufacturing various types of fluid end valve and seats for both frac pumps and mud pumps, covering various models for the most dominant pumps in the market.

T-seals are three piece seals with an elastomeric lip and hard plastic anti-extrusion rings, it is proved to be of long time service. The standard design will fit into an o-ring gland and can be machined or net moulded.
