Spiral wound gaskets are the most common metal gasket used in industrial equipment. Spiral wound gaskets that are correctly selected and installed can withstand high temperatures and pressures, thereby preventing leakage during their
expected service life.

The spiral wound gasket is composed of three parts: the outer ring, the inner ring and the sealing element. The function of the inner ring is to act as an additional compression stopper to prevent internal bending of the sealing element.
It also forms a physical barrier between the sealing element and the process flow, shielding heat and media while preventing corrosion.

Color plays an important role in spiral wound gaskets. The color of the outer ring and the color of the stripes along the ring are important indicators of the material inside the gasket.
