is an innovative and new design in seal ring technology. It is a seal ring that provides superior performance and durability compared to Teflon and traditional seal ring materials. It reduces gas permeation and promotes higher dimensional stability. With its unique o-ring design, it performs in harsh environments where other elastomers fail. It is a fully machined product, rather than a molded seal. It comes standard with viton or peroxide cured buna o-rings and can be easily changed (if needed) with standard o-ring sizes. Other elastomers can be used based on service requirements. This simple snap together design allows for quick and easy orifice plate changes.
