Bonded seals for completion tools

Nylon BX R RX style Test Ring Gasket is good for valve pressure test. JST Nylon ring joint test gaskets are a no damaging method to test and re-certify ring type joint flanges.

High-pressure Rotary shaft seals are one bidirectional rotary seal which can bear both sides of pressure and alternating pressure. It is made with slip ring and o-ring/square ring.

JST's Packer elements are flexible elastomeric components that are used to seal between the outside diameter of the production tubing and the casing, liner or wellbore.

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.

PDR rotary shaft seal extends the boundaries of elastomeric radial shaft seals, utilizing advanced materials and design techniques to provide optimal sealing performance for each application. The result is a superior sealing solution that retains a compact sealed casing.

Piston seals are working to seal in fluid, thus preventing the flow of fluid across the piston, allowing pressure to build up on one side of the piston.

The FDR seal is made of a helical wound spring and a polymer jacket, which is mainly used as a Flange external face seal.

ptfe wear strips can keep the piston centered as well as preventing metal-to-metal contact.
