Spiral Wound Gasket is the ideal gasket in the semi-metallic category.

A narrow strip of V-shap metal hoop is spirally wound under tension with a filler cushion between the lami nation of the metal and is spot-welded at both ends.

Resistance to high temperature and high pressures.

Great resilience which allows the gasket to adjust automatically to change in operating conditions, such as pressure and thermal shocks, vibrations etc.

Excellent sealability is maintained with comparatively small gasket area.
Good tolerance for flange surface finish irregularities.
Can be designed to any dimensions economically in circular or moderately noncircular shape.
Available in a variety of hoop metals and filler materials to satisfy specific operating conditions.
