Graphite spiral wound gaskets

   Spiral Wound Gasket

Spiral wound gaskets have proven themselves to be the most reliable sealing element for use in difficult, critical and arduous duties. Spiral wound gaskets are used in Refinery, Petrochemical, Chemical, Steam lines and Process Industries, where they have many advantages over older types of gaskets,.

These gaskets are manufactured to International specifications such as BS, API, ASME, DIN, or to customer's specification,.

We also have huge capacity to produce precision machined components.,
