SPIRAL WOUND GASKETS

Spiral Wound  gaskets are suitable across a wide range of fluctuating service pressure – up to 250 bar – and temperature – from -200°C to 1000°C – depending on their construction.

The sealing element consists of a V-shaped metal strip spirally wound in combination with a sealing material filler.

The metal strip provides outstanding resilience, while the flexible sealing filler guarantees excellent sealing.
