R-type gasket
The ring joint gasket was originally developed for high-pressure/high-temperature applications in the petroleum industry, mainly used for drilling and completion equipment in oil fields.
However, today this product line can also be found on valve and pipeline working devices, as well as some high integrity pressure vessel joints.
The manufacturing of R-type gaskets complies with API 6A, 6B, and ASME B16.20 and is suitable for API ASME/ANSI B16.5 flanges. In elliptical and octagonal configurations, these two types are interchangeable modern octagonal groove flanges.
