Spiral vand washers are one of the most reliable and widely used types of sealing items, suitable for high temperature and pressure for use in refinery, petrochemical, chemical, steam and process industries.

Spiral vand washers have the ability to recover under the influence of fluctuating loads caused by fluid pressure and flange surface temperature changes.

The sealing part of spiral gaskets consists of a pre-made metal strip and a softer and more compact filler made of graphite, PTFE or mica.According to different conditions, spiral vand washers can be made and used by combining a wide range of filler materials and metals to resist destruction caused by chemicals and temperature; which is wrapped in several alternate rounds to create more strength and withstand higher pressure with a V-shaped cross-sectional surface and is compressed, fills the microscopic spaces and irregularity of the flange faces, and then forms a complete seal and sealing It does better. The elasticity and pressure resistance of this product due to the spiral shape of the layers are the factors that make this gasket stand out as a suitable option for use in various applications.The mentioned gaskets are suitable for standard flanges from size "1/2" to "60" in different working classes based on Asme B16.20, BS 338 standards and also custom produced outside the standard.
