JST Seals

Backup rings   play a vital role in preserving the integrity of seals within pressurized aerospace hydraulic systems, minimizing leakage, and extending the lifespan of the components they protect. What are Backup Rings? The back up ring material could be PEEK, modified PTFE. PEEK™ back-up rings are designed to prevent extrusion in elastomer O-ring sealing systems. These rings are designed to close off the sealing system's extrusion gap and support the primary seal, especially under high-pressure conditions. Elastomer O-rings  serve as effective seals for dynamic and static applications in hydraulic and pneumatic equipment systems. A drawback of elastomer O-rings is their tendency to extrude into the clearance of mating surfaces with increasing pressures and temperatures. Higher temperatures impose a severe burden on the physical and mechanical properties of elastomer O-rings, which further increases their tendency to extrude. The combination of high pressures and high temperat...

  Application of   FFKM in O-Rings , seals and gaskets can meet the chemical resistance and high temperature requirements of strictly regulated industries. Equipment operators in critical and strictly regulated industries such as oil and gas, chemical refining and processing, aerospace, pharmaceutical and food processing, and semiconductor chip manufacturing all face a common pain point: How can the elastomeric materials in the O-rings, seals, and gaskets that keep the machines moving meet the stringent requirements of their environments? The answer is  Perfluoroelastomers (FFKM) , a family of chemically and heat-resistant elastomers that combine the chemical resistance of polytetrafluoroethylene (PTFE) with the flexibility and elasticity of standard fluorocarbon elastomers (FKMs). FFKM was born and is now widely used in many industrial processes. However, due to the wide variety of compounds currently available, there are many factors to consider when selecting FFKM mate...

  JST makes custom and standard   PEEK back-up rings . The PEEK back-up ring is made of polyetheretherketone (PEEK) material. PEEK is a high-performance thermoplastic with exceptional properties. It has high temperature resistance, capable of withstanding extreme temperatures without significant degradation. It also exhibits excellent mechanical strength, providing durability and reliability. PEEK is chemically resistant to a wide range of substances, making it suitable for use in harsh environments. Additionally, it has low friction properties and good wear resistance. The choice of PEEK for the back-up ring ensures reliable performance in various applications, such as in hydraulic systems and sealing applications. It can help prevent extrusion of elastomeric seals under high pressure, enhancing the overall sealing integrity and longevity of the system. Industries such as oil and gas require demanding working conditions. PEEK back-up rings can be used in multiple down-hole dr...

Rubber seals   and   metal seals   are two common types of sealing components used in various applications across industries. Each type of seal has its own advantages and differences that make them suitable for different purposes. Let’s explore the differences and advantages of rubber seals and metal seals: Rubber Seals: Advantages: Flexibility: Rubber seals are flexible and can conform to irregular surfaces, making them effective in sealing applications where there may be slight imperfections or movement between mating surfaces. Sealing Properties: Rubber seals offer excellent sealing properties, providing effective barriers against liquids, gases, dust, and other contaminants. They can create a tight seal to prevent leakage and maintain the integrity of the enclosed environment. Vibration Dampening: Rubber seals have inherent vibration dampening properties, making them suitable for applications where shock absorption or noise reduction is required. Differences: Material...
