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 ...
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...
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 sur...
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 el...

Sealing at cryogenic temperatures has its own unique set of challenges. To provide superior protection against leakage in cryogenic valves for LNG, cryogenic seals should be designed with the following properties in mind: Jacket material that tolerates thermal cycling A spring energizer to compensate for shrinkage Anti-extrusion lip geometry JST has a wide range of solutions for cryogenic sealing ...
SPGW hydraulic seals are designed for heavy-duty applications, often used in hydraulic cylinders, offering a combination of wear resistance, low friction, and durability. Here are some key features of SPGW hydraulic seals: 1. Material: Bronze-filled PTFE (Polytetrafluoroethylene): Provides excellent resistance to wear, extrusion, and deformation. NBR/Nylon: Often combined with PTFE, these provide ...
The environments in the oil and gas industry are extremely harsh. High pressures, temperatures, and corrosive substances pose significant challenges to equipment reliability. Seals are essential to prevent the leakage of oil, gas, and other fluids, ensuring safe and efficient operations. A seal stack is a combination of multiple sealing elements designed to provide a reliable barrier. It cons...
