High-performance spiral wound gaskets from South Eastern Gaskets, built for reliable sealing in high-pressure and high-temperature industrial applications.
In industries where operational conditions are demanding and equipment is subjected to extreme pressure and temperature, the importance of selecting the correct gasket cannot be overstated. The right gasket ensures both safety and efficiency, minimising downtime and preventing costly leaks. Spiral wound gaskets are among the most reliable sealing solutions for critical environments, valued for their resilience, adaptability, and essential role in high-performance industrial systems.
How Spiral Wound Gaskets Differ from Other Gasket Types
Spiral wound gaskets differ from conventional flat gaskets by combining metal and filler materials instead of relying on a single material. The metal, usually stainless steel, provides structural strength, while the filler, such as graphite or PTFE, ensures a dependable seal. This layered design enables superior performance under fluctuating pressure and temperature conditions, surpassing the capabilities of rubber, fibre or compressed non-asbestos gaskets.
Additionally, their ability to return to their original shape after compression makes spiral wound gaskets especially suited for applications involving cyclical pressure or thermal variations. This flexibility and durability are particularly beneficial in industries such as oil and gas, chemical processing, and power generation, where equipment is frequently exposed to extreme operational conditions.

Why Spiral Wound Gaskets Excel in High-Pressure Environments
Spiral wound gaskets are engineered to withstand high-pressure conditions, with metallic windings that resist blowouts and deformation under heavy loads. Their robust design maintains sealing performance even under varying internal forces, making them suitable for pipelines, pressure vessels and flanged joints. Combined with chemical-resistant filler materials, they are ideal for demanding environments such as refineries, steam systems and high-temperature heat exchangers.
How to Select the Right Spiral Wound Gasket
Choosing the appropriate spiral wound gasket for your application is essential to ensure optimal performance and longevity. Here are three critical considerations:
• Understand the Operating Conditions – Start by assessing the system’s pressure and temperature to choose the right gasket. Match the spiral wound gasket to the appropriate pressure rating to ensure reliable performance.
• Choose the Appropriate Materials – Choose the right metal winding and filler based on temperature, media, and mechanical needs. Stainless steel with graphite suits high heat, while PTFE works for harsh chemicals.
• Verify Flange Compatibility – Ensure the gasket matches the flange in size, ring configuration, and thickness to prevent misalignment and seal failure.
