JST Seals

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...

  When designing a   cryogenic seal ,   the first step is to determine the operating temperature range of the seal. Typically, cryogenic seals operate below -65 degrees Fahrenheit. When designing seals of this level (high temperatures are around 300 degrees Fahrenheit), it is necessary to understand what degree of leakage control is required on the low temp end. However, there may be an allowable leakage rate which allows for reduced drag. When requiring zero leak, the drag in the system is often increased to support some elastomeric contact with a dynamic surface. In the case of  static seals , elastomers span this range although increased squeeze may be necessary. JST typically designs within the above range. While -65°F is extremely cold, it is not considered cryogenic. Liquid nitrogen at -320°F (-195°C) requires special hardware and seal material considerations. First, many projects and applications don't utilize lubricant in dynamic applications. To improve seal...
