material is usually soft iron or low carbon steel.
this type of gasket has three main functions:
• it is used in pressure testing to minimize
damage to flanges.

seals while protecting the flange surfaces.
• it provides increased assurance against
corrosion, which can occur between
conventional ring type joints and the
engaged surfaces of the groove.
a wide range of standard sizes are available,
