  • How to choose spring energized seals materials?
    • July 16. 2021

    JST's Spring Energized Seals, also called Lip Seals, are normally comprised of a machined polymer jacket and a spring energizer. They are available for rod, piston, and rotary applications, and can be manufactured in a variety of polymer materials depending on each application requirement. Our seals can be made of different PTFE materials, from Virgin PTFE or PTFE with fillers of di...

  • What type of PTFE seals rre you looking for?
    • July 19. 2021

    PTFE (Polytetrafluoroethylene) material is widely used in hydraulic and pneumatic seals. PTFE gets high melting point in excess of 300℃, has good resistance to ageing, as well as low coefficient of friction. PTFE seals are used to enhance friction capabilities, withstand high pressure applications, and extend seal life in applications outside the parameters of elastomeric seal use. We offer a rang...

  • What are Spring Energized Seals?
    • December 15. 2021

    JST Seals produces a full range of spring energized seals that are used in a wide range of applications. The Spring Energized Seals are normally comprised of a machined polymer jacket and a spring energizer. The polymer jacket can be made of different materials, from Virgin PTFE or PTFE with fillers, to PEEK and UHMWPE seals profiles. Spring configurations such as helical spring energized seals, s...

  • How to install valve stem seals?
    • March 14. 2022

    Valve seals precisely control the amount of oil entering the valve stem system, making them critical components in maintaining your engine’s compression levels. Having a valve stem seal that works correctly within any of your applications can save you time and money by eliminating the need for lengthy engine repairs and replacements. But how to install valve stem seals, please see below. Installat...

  • What are the reasons for trying to use metal spring energized seals in semiconductor applications?
    • August 03. 2022

    The high-performance metal spring energized seal is made of high-performance polymer, which can solve the sealing challenges of rotating motion, friction resistance limitation, plane change along the sealing surface and dynamic sealing. PTFE spring energized seals are designed for extreme low temperatures ranging from -270 ° C to extremely high temperatures, sometimes exceeding 300 ° C. The specif...

  • What kind of spring energized seals that JST carry?
    • December 14. 2022

    JST's Spring energized seals are designed for static rotary and reciprocating applications in temperatures from cryogenic -196℃ to 300℃; and pressures from vacuum to 70Mpa, movement speed reaches 20M/S to survive the most corrosive environment. Jacket material: Virgin PTFE                temperature :  -200~+230℃ PTFE+ carbon fiber       ...

  • Spring Energized Seals - Industry Application
    • December 29. 2022

    JST Seals manufactures spring energized seals of different materials. Spring energized seals are composed of two parts: a PTFE or polymer jacket and a corrosion-resistant, metal energizer spring. comparing to other seals, the seals provide better performance over elastomeric seals and metal gaskets that typically fail. Its sealing jacket is a U-shaped shell made of high-performance non-metallic po...

  • What Is PEEK?
    • January 15. 2023

    PEEK is a colorless organic thermoplastic semi-crystalline polymer with excellent mechanical and chemical resistance properties. It’s high-resistance to terminal degradation makes it useful in oil and gas environments. The processing conditions used to mold PEEK can influence the crystallinity and hence the mechanical properties. As with PTFE, PEEK has several benefits for oil and gas companies. I...
