R SERIES
Style R is the original ring joint gasket design which can be used in modern flanges having the standard ring joint flat-bottom groove as well as older flanges with the round bottom groove style. The octagonal version was introduced to provide increased contact area resulting in higher sealing efficiency.
R series ring-type joint gaskets are available in oval and octagonal designs. The oval design can be used in older round bottom gland designs, while both can be used in flat bottom designs. R series is available up to 5000 PSI.
