Exhaust spiral wound gaskets are used to seal flanged joints in vehicle exhaust systems, preventing leaks of high-temperature gases and ensuring reliable performance under thermal cycling and vibration.

This article examines the suitability of special material spiral wound gaskets for high-temperature applications, analyzing their thermal resistance, material properties, and performance limits.

Non-circular spiral wound gaskets are custom-shaped to seal non-round flange geometries, unlike standard round types made exclusively for circular flanges.

This article explores the key distinctions between standard spiral wound gaskets and nuclear grade versions, including material specifications, manufacturing standards, and performance criteria required for critical nuclear applications.

Standard spiral wound gaskets are sized to match common pipe flange dimensions per ASME B16.20, typically ranging from 1/2 inch to 24 inches in nominal diameter. The gasket thickness is usually 0.125 inches for standard-duty and 0.175 inches for heavy-duty applications, with inner and outer ring dimensions precisely specified to seat within the flange face.
