Spiral wound gaskets are a popular type of mechanical gasket, produced by winding a V-shaped metal strip with a softer filler material. These gaskets can withstand fluctuating pressure and temperature variations and are a good choice for critical applications. The metal strip allows the filler to flow into imperfections in the flange surfaces and provides good mechanical resistance.

Spiral wound gaskets are available in several styles. These gaskets can be ordered in a wide range of materials, with several unique features. Some styles are designed for high-temperature applications, while others are suitable for low-temperature applications. A spiral wound gasket can be ordered in a range of materials, including carbon steel, graphite and monel.

Spiral wound gaskets are often made of graphite or PTFE. These materials have exceptional corrosion resistance and can withstand high temperatures. Spiral wound gaskets can also be used in low-temperature applications, such as in a pump or a valve.

Style R spiral wound gaskets are manufactured to a thickness of 0.125" and have a solid inner metal ring that provides compression stop and fills the annular space. They are suitable for male and female flange connections. Some styles are available in round and oval shapes.

Spiral wound gaskets are available in a variety of thicknesses. A typical thickness of 0.125" (3.2mm) is recommended for broad seats. For high-pressure applications, thicker gaskets are available.
