Spiral Wound Gasket

Spiral Wound Gaskets, ASME B16.20 Spiral Wound Gaskets Supplier in Mumbai, India

Unifit Metal Alloys is a manufacturer, supplier and exporter of Spiral Wound Gaskets in Mumbai, India, supplying sealing solutions for industrial piping, pressure equipment and process systems. Our Spiral Wound Gaskets are manufactured using a controlled winding process in which a thin metallic strip and suitable filler material are wound together around a winding mandrel to form a secure and resilient sealing element.

The construction of a Spiral Wound Gasket allows the metal winding and filler material to work together under compression, helping the gasket maintain sealing performance across varying pressure and temperature conditions. The dimensions, winding density and material combination can be selected according to the service requirements and flange arrangement.
