API R Ring Joint Gaskets

Smith Gaskets offers API R Ring Joint Gaskets. The R-Type ring gasket are found in two shapes, Oval or Octagonal. Both shapes have the same pitch diameter as the flange groove they communicate to. These gaskets are used in pressures up to 10,000 PSI. The octagonal type has a higher sealing co-efficient than the oval, therefore it is the most wanted shape. The oval type is the only gasket that will fit a bottom radiused groove. Both the Gaskets can be used in Flanges with flat bottom v-grooves. OVL and OCT is used as abbreviation for Oval and Octagonal shapes respectively.
