Spiral Wound Gaskets

Additional Details

AIG Spiral Wound Gaskets are designed to withstand extreme temperatures and pressures while maintaining effective sealing. They are made by spirally winding alternating strips of metal and soft filler materials (such as graphite), providing resilience and strength. These gaskets are highly versatile and can be manufactured with or without inner and outer rings made from Carbon Steel or Stainless Steel, depending on the pressure-temperature rating.
