JST produces different material spring energized lip seal. Jacket material such as PTFE, PEEK, TFM. Spring material include 316ss or Alloy spring. For different working conditions, we use different seal designs and materials. If seal works at pressure over 6000PSi, PEEK back up ring is needed. For -196°C, we would use material TFM+Alloy spring. JST has ability to produce different dimensions of sp...

FS casing and tubing seals are uniquely designed sealing elements that provide excellent sealing in areas where high seal deflection is required. The design features of this seal allow the component to compensate for changes in piping, housing, or large diameter parts. The use of metal clamping springs provides extrusion resistance. The open coil has no initial tension during manufacturing, so the...

There are many reasons for seal failure, including long-term storage in less than ideal conditions. Rubber may crack, harden, soften or degrade, making it unsafe for its intended use. Most seals have a widely accepted shelf life, which helps manufacturers prevent catastrophic failures caused by old seals. Maintaining the seal throughout its intended shelf life requires providing a storage environm...

Hydraulic cylinders are used to perform work in a variety of different situations and applications on a daily basis. In order to contain pressurized fluid and maintain its movement in the hydraulic cylinder system, two basic types of complex configurations of high-performance seals are required: static seals and dynamic seals (supported by guide rings). There are certain types of seals in each cat...
