Below is a list of Spiral Wound Gaskets manufacturers from Akron, Ohio. Spiral wound gaskets are composite metal-filler rings used for the sealing of pipes, especially between flanges. Flanges are hardware used to connect sections of pipes, tubes and other materials transmission equipment. They usually are connected with fasteners like bolts and are a good method for creating secure connections, but they often are not fluid-tight without being fitted with gaskets.
