FLEXWOUND® BS Low Stress Spiral Wound Gasket

The BS and BSI gaskets are specifically designed to be used in those applications where a low bolt torque is required. Traditional spiral wound gaskets have the steel winding protruding above the compression stop. BS and BSI gaskets instead have the filler material protruding above the metal winding and the guide ring. This results in a perfect seal ability achieved with a lower loading stress compared to tradisonal spiral wound gaskets.
