BOP inner and outer seal

Outer wireline valve seals are used in various type of Blow Out Preventors (BOP's).

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.

XTP is Double acting piston seals, composed of PTFE piston sealing ring, O-ring and X ring, and is used for the piston bidirectional seal of hydraulic cylinder. Especially suitable for separating two different mediums.  

The spring energized seal is widely used in medical equipment, which is generally composed of a corrosion resistant spring and a seal ring made of U-shaped filled PTFE/UPE material.  

UNS UHS is a lip-seal which can be used for both piston and rod .

The ball valve seat is responsible for sealing the fluid inside and uniformly distributing the seating stress. A leak of ball valve in petrochemical application could be environmentally devastating.

Many industries use FFKM O-rings in critical applications where sealing failure is strictly prohibited. These industries include chemical processing, energy, semiconductors, pharmaceuticals, oil and gas recovery, aerospace, and other industries.

JST's centralizer rubber fins is made according to customer requirements. The centralizer fin has a retrievable, reseatable, flexible design. This Rubber and metal reinforced rubber centralizer fins are available for a variety of MWD (measurement while drilling) tools and oil well logging and monitoring instruments.
