FJSEALS helical spring energized seal is a single-acting seal consisting of a wound corrosion resistant metal spring installed in a U-shaped jacket. The helical shape spring affords a relatively high load versus deflection range resulting in a seal product that provides very tight sealing. This makes it ideal in low pressure, even vacuum applications. As a highly loaded product, helical spring energized seal is ideally suitable when dynamics are very slow or static.

Helical springs are spiral-wound springs made from flat metal strips and are used in RS18 helical spring energized seals and spring energized face seals. They have a higher unit load and shorter deformation range than other types of springs, making them ideal for static and slow dynamic applications. RS18 seals and spring energized face seals are the preferred choice for vacuum, gas, and low-temperature applications.

We have adopted world-class high-precision sealing processing equipment, pure imported raw materials and strict quality management systems to rapidly produce precision sealing products of any shape, size, and material to meet customer needs.

Helical spring seals are used in various pumps to ensure a seal between the impeller and shaft, preventing fluid leakage.
Helical spring seals are used in various types of valves to control fluid flow and ensure valve sealing.
Helical spring seals are used for sealing at pipeline connection points to prevent liquid or gas leakage.
In marine engineering and shipbuilding, helical spring seals are used for waterproofing, wave resistance, and preventing seawater intrusion.

As a professional manufacturer of spring seals, FJSEALS is capable to produce spring-energized seals in a wide range of sizes, from 5 mm to 2.6 m in diameter.
