Double jacket gaskets are typically constructed with a metal outer shell and a soft filler core. Common jacket materials include stainless steel, carbon steel, copper, and nickel alloys, while the filler is often made from flexible graphite, PTFE, or ceramic fiber.

This article explores whether pure expanded graphite gaskets can reliably perform in steam applications, focusing on their thermal stability, oxidation resistance, and sealing integrity under high-temperature conditions.

Spiral wound gaskets use alternating layers of metal and filler for flexibility under thermal cycling, while metal jacketed gaskets enclose a soft core in a metal shell for rigid, high-temperature sealing in exhaust systems.

Discover which special materials, such as Hastelloy, Monel, and titanium, provide superior corrosion resistance in spiral wound gaskets and how to select the best option for aggressive chemical environments.

Learn the correct steps for installing non-rounded spiral wound gaskets to ensure a reliable seal and prevent leakage.

Spiral wound gaskets are commonly used in high-pressure and high-temperature applications such as oil and gas, petrochemical, and power generation industries. They are suitable for pressure classes ranging from 150 to 2500, making them ideal for flanged joints, heat exchangers, and boiler systems.
