Spiral gaskets

These gaskets are constructed with a metallic guide ring, metallic winding and a filler element. The metallic winding, of special profile, provides excellent resistance, compensating the changes in operational conditions such as variations of pressure and temperatures, vibrations, thermal shocks, etc. The filler materials fill the irregularities of the flanges, assuring an airtight seal. Its external guide ring has the function of centering the gasket in the flanges and gives the sealing elements additional resistance to the flow pressure, avoiding also excessive bolt torque.


The WR type gaskets are suitable for applications that have pressure and temperature variations. They are also used to seal in processess where fluid pressures vary.
