Driven by the industry’s need for safe, effective sealing solutions for increasingly demanding applications, Flexitallic invented the spiral wound gasket in 1912.

Not satisfied with inventing the iconic spiral wound gasket, Flexitallic have continued to innovate by developing world leading materials. Thermiculite® is often used as a filler material to provide resistance to temperature, chemical attack and corrosion. Through precision engineering, the spiral wound gasket, available in unlimited configurations of high quality metals andmaterials, is individually tailored to meet the demands of each application.

Globally acknowledged to provide a superior seal in the most exacting of conditions, its flexibility and recovery gives it a unique ability to cope with the effects of high pressure, wide temperature fluctuations and bolt relaxation. Spiral wound gaskets are found in a host of applications across the world, from small diameter turbine gaskets, to HP heat exchangers.
