JST Seals

  Spring energized face seals  are often used in static sealing applications.  PTFE face seals  offer advantages over traditional O-rings in terms of pressure handling, chemical compatibility, and operating temperature range. Often used in cryogenic applications. Face seals are designed for either internal or external pressure, but not both. Product Type Product Description Technical Data Working temp Pressure Speed FHB 1. The  end face seal  design of helical spring combined with arc lip, with pressure coming from the inside direction. 2. With high spring load, it is the best choice for low temperature, gas and low pressure static flange sealing applications. 3. Application: valves, compressor cylinders, cryogenic equipment, rotary joints, etc. -110℃ ~260℃ Standard type 20MPa extended or blocked country type 40MPa - FVB 1. The end face sealing design of the V shaped spring combination inclined lip, with pressure coming from the inside direction. 2. It...

  A   hydraulic cylinder seal   is a critical component in hydraulic systems, designed to prevent fluid leakage and maintain pressure within the cylinder. These seals ensure the efficient operation and longevity of hydraulic cylinders by keeping the hydraulic fluid contained and separating different fluid areas to avoid contamination. Types of Hydraulic Cylinder Seals 1. Rod Seals :  Prevent fluid leakage from the cylinder along the piston rod. 2. Piston Seals :  Seal the piston to prevent fluid from leaking across the piston. 3.Wiper Seals/Scrapers:  Remove contaminants from the piston rod as it retracts into the cylinder. 4.Buffer Seals:  Absorb pressure spikes and help protect the rod seals. 5.Wear Rings/Guide Rings:  Provide a bearing surface to support the piston or rod, reducing wear and maintaining alignment. Common Materials Material Codes: -NBR -FAB -FKM -PTFE -PU -UPE -EPDM Working temperature: -30~+100 ℃, Short term up to +120 ℃ -30~+10...

  JST  KALFLUO 8520  is a kind of  FFKM  material which is specially cured for very high performance  applications, with high purity, good chemical resistance and heat stability properties. It is mainly used for  semiconductor  manufacturing applications, which is an ideal sealing material for most dry ( plasma  etching, PECVD, LPCVD, metal CVD, PVD, ALD, plasma cleans) and wet semiconductor processes (wafer cleaning, polymer removal, wet etching, polishing). It is suitable for applications at temperatures ranging from –10°C to 300°C. Physical properties of KALFLUO 8520: Fluid resistance properties of KALFLUO 8520: Metallic element detection (Solvent immersion) of Kalfluo 8520: Detection of metal element precipitation in 18M Ω UPDI water at 80 ℃ for 720 hours, parts per billion (ppb, ug/L) ICP-MS-MS) Test result: Remarks: 1- Detection limit value: 1ppb; 2- ND=Not detected.
