A butterfly gasket is a type of gasket that is used in flanged piping systems to create a seal between two pipes or between a pipe and a valve or other equipment. It is named after its shape, which resembles a butterfly with two wings.

Butterfly gaskets are typically made from elastomeric materials such as EPDM, Nitrile, or Viton. They have a circular shape with a thin profile, and are designed to fit into the groove of a flange. When the flange is tightened, the butterfly gasket is compressed between the two surfaces, creating a seal that prevents leakage.

Butterfly gaskets are commonly used in the food and beverage, pharmaceutical, and chemical processing industries, as well as in water treatment plants and other industrial applications. They are preferred over other types of gaskets, such as full-face gaskets, because they are less expensive, easier to install, and require less bolt load to achieve a seal.

When choosing a butterfly gasket, it is important to consider the material, temperature range, pressure rating, and chemical compatibility. Butterfly gaskets are available in a range of sizes and thicknesses to fit various flange configurations. Regenerate response
