JST's Spring Energized Seals, also called Lip Seals, are normally comprised of a machined polymer jacket and a spring energizer. They are available for rod, piston, and rotary applications, and can be manufactured in a variety of polymer materials depending on each application requirement. Our seals can be made of different PTFE materials, from Virgin PTFE or PTFE with fillers of di...

Piston seals for hydraulic cylinders are quite similar to rod seals, but they are attached to a piston that seals a bore or cylinder housing. These seals are specifically designed to prevent pressurized fluid from leaking down in between the piston and the bore, while the piston itself is pushed down the cylinder bore. The high-quality hydraulic piston seals from JST will keep the pistons in your ...

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...

PTFE seal designs were developed to incorporate energizing elements such as O-Rings and metallic springs. These energizers ensure the PTFE seal is always in contact with the sealing surface. JST utilizes three different types springs to internally energize PTFE and other polymer seals, each with its own advantages. Below, we will discuss in details for some of the advantages of cantilever V-spring...
