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...

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...

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...
