50High pressure ball valve seat seal
The spring energized seal can select different spring forms and sealing lip designs according to the applications such as dynamic, static, internal and external pressure, resulting in impassable sealing force and compression deformation. The spring force will affect the performance, friction and wear performance of the jacket. The compressible stroke determines the compensation ability of the jacket for the wear of the sealing lip and the dimensional tolerance variation of the sealing groove.
Customized products can be developed according to customers' needs.

The spring energized seal is a high-performance Teflon seal with a special spring inside.
The FHB seal design of the spiral spring combined arc lip, and the pressure comes from the inside.
LNG Lip Seal For Filling Guns is commonly used in LNG (liquefied natural gas) filling guns.
V-Packings are used in various Oilfield Downhole equipment such as various Valves etc. V-Packings are extremely suitable for usage in medium to heavy duty applications. Vee Packings accept low and high pressure while operating in the most extreme conditions and also if there exists any misalignment between the sealing gaps.
This is sealing product developed by JST to meet the increasingly demanding sealing needs of equipment manufacturers and users in semiconductor, petrochemical, mechanical seal, instrumentation, energy, biopharmaceutical, food and medical industries.
Rotary shaft seals with PTFE ring have been specially developed for use in harsh conditions. They are used when shaft seals with classic elastomer lips reach their performance limits.
JST's metal end cap seal is elastomer bonded onto 2 steel caps. This provides high level of extrusion resistance.
