  • JST 3" FKM S seal passed API 6A 21st Edition Annex F PR2 test
    • August 03. 2022

    S Seals is made from elastomer and two metal garter spring. The metal garter spring is incorporated into the elastomeric seal element. The one-piece S seal eliminates the installation issues that may occur when using multi-component seals. It can be stretched into place without splitting or damaging the non-extrusion components. S seal can be manufactured to accommodate almost any gland size, incl...

  • 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 are the common trimming methods for rubber sealing rings
    • August 03. 2022

    Trimming of rubber seals is an essential process in the production of rubber products. The quality of trimming process directly affects the production efficiency and quality of rubber seals. Common trimming methods of rubber sealing ring are as follows: 1. Manual trimming. Manual trimming is the most traditional trimming method, which trims the excess glue edge step by step along the outer edge of...

  • What are the advantages of turning hydraulic seals over molded hydraulic seals
    • July 27. 2022

    The processing technology of turning seals is different from that of traditional molded seals. The raw materials for turning hydraulic seals are blank barrels formed by high-pressure extrusion of raw materials after heating and melting, and then the hydraulic seals are turned by special turning CNC seal processing equipment that programs various seal data through software. Turning hydraulic seals ...

  • Precautions for installation and storage of PTFE seals
    • July 27. 2022

    PTFE seal is the core of hydraulic equipment and the guarantee for normal operation of hydraulic equipment. Therefore, the installation of PTFE seals is very important. Any error in the installation process may affect the sealing performance, and then affect the normal operation of hydraulic equipment. Therefore, it is necessary for operators to understand the installation precautions of PTFE seal...

  • Compound suitable for FS seal and S seal
    • July 25. 2022

    JST compound H3385 is a hydrogenated acrylonitrile-butadiene-rubber commonly referred to as HNBR or HSN, with excellent physical characteristics, outstanding abrasion resistance and chemical resistance to common hydraulic fluids, sour oils/gases(H2S) and crude oils. H3385 has been optimized to withstand the risk of rapid gas decompression(RGD) or explosive decompression(ED)or anti-explosive decomp...
