The three main types of standard groove designs are Industrial Static also called Radial, Industrial Reciprocating also called Dynamic, and Face Seals also called Axial or Flange. Radial and Dynamic seals require the presence of a diametrical clearance gap for installation. Face seals have no clearance gap, but consist of a groove cut into one flange with a flat mating flange bolted together to give a surface to surface contact.
