Spiral Wound Gaskets

Spiral Wound Gasket - Carbon Steel Outer Ring Spiral Wound Gasket - Stainless Steel Outer Ring

Spiral wound gaskets are expertly crafted using a metallic winding strip combined with layers of softer sealing materials such as graphite, compressed fibre, or PTFE. This design ensures reliable sealing performance under demanding conditions, with the filler material allowing the gasket to maintain integrity despite fluctuating pressures. Recognised for their durability, these gaskets are ideal for high pressure and temperature environments, making them a trusted solution across various industrial applications.

Applications

Widely utilised in sectors requiring robust sealing solutions, spiral wound gaskets are suited for heat exchangers, pipelines, flanges, and valves operating under high-pressure and high-temperature conditions.

Key Features

  • Temperature: Up to +1000°C, depending on the materials used.
  • Exceptional compatibility with a broad spectrum of media, including steam, chemicals, oils, and hydrocarbons.
