The products used to seal these pipe joints are known as gaskets. A flange gasket is the particular style of gasket utilized to create a seal when two flanged pipe ends are bolted together. The most common use for gaskets is in the services industry, where water pipes need to be sufficiently sealed to prevent water leaks, loss of pressure, or external foreign contaminants entering the pipe.
Spiral wound gaskets are constructed of a thin strip of metal (such as metal wire) and a nonmetallic filler material; the metal strip (metal wire) and the nonmetallic filler material are wound together, the end result being the spiral wound gasket.
