Gaskets are critical sealing devices that occupy space between two or more surfaces to prevent leaks. They are available in a wide range of designs and materials, depending on the intended use. Metal gaskets are a specific subcategory that is effective for applications with extreme temperatures, high pressure, and chemical exposure where elastomeric and other materials will not work effectively.

Types of Metal Gaskets
Metal gaskets come in several shapes, sizes, and configurations. Each design offers unique benefits for particular applications and operating conditions where other non-metallic materials will not work.

Spiral Wound Gaskets
A spiral wound gasket consists of a V-shaped stainless steel strip spiraled around a non-metallic filler. Common fillers include flexible graphite or PTFE. A solid outer ring ensures optimal pressure distribution and reduces the potential for creep.

Metal Jacketed Gaskets
Metal jacketed gaskets are metal outer shells containing filler material, which is typically soft graphite, PTFE, or composite fibers. The filler material provides flexibility for an effective seal, while the metal jacket offers protection from corrosion, high pressure, and extreme temperatures.

Ring Type Joint Gaskets
Ring type joint (RTJ) gaskets are designed specifically for high-pressure, high-temperature operations. Composed of solid machined metal, RTJ gaskets are exceptionally durable, with outstanding seal integrity. They are preferred for the oil and gas industry, especially for wellheads, drilling, and other extraction operations.

Kammprofile Gaskets
Kammprofile gaskets feature a unique design: a solid metal core with serrated edges and covered with a soft sealing material. These gaskets are ideal for applications that require low-stress seating. The alternating soft and hard materials establish a strong seal and prevent lateral flow, without placing excess pressure on the substrate.

Corrugated Metal Gasket
Corrugated metal gaskets (CMGs) are made of a solid metal core and can also be covered with flexible graphite or PTFE. The core features concentric grooves on both sides, and the coating aides in sealing the joined materials from pressure as the gasket tightens. CMGs are effective in low-pressure applications, while retaining resilience and flexibility at high temperatures.
