The American Petroleum has standardized the underwater utilization
of ring gaskets with the SRX and the SBX series rings. There is no
dimensional difference between the standard RX and SRX or the BX
and SBX. They will fit into their appropriate flange designated
numbers. The "S" prefix identifies a gasket as having intersecting
vent holes, allowing a pressure less metal-to-metal initial contact
between the gasket and flange groove, while made up underwater. For
pressure class ratings on these gaskets refer back to their non "S"
type standard gasket classification chart for the RX-Series and
BX-Series. Gaskets that have been torqued initiating a
metal-to-metal seal should be discarded and not reused.
