Style XR-RJ is a replacement gasket for solid metal oval or octagonal API Ring Joint gasket. These gaskets may be used as a replacement when spiral wound gaskets are preferred or when the gasket groove is badly worn, thereby saving the cost of flange replacement.
NOTE: O.D. Dimensions of gaskets are nominal. Actual dimensions are approximately 1/32” less to incur proper assembly in rings.
