Ring joint gaskets are made for a variety of metals from carbon steel to Alloy 825.  Common cross-section shapes are oval and octagonal, many others are available.  The hardness of the ring joint should always be less than the hardness of the flange to prevent flange deformation.  A wide range of sizes and materials are ready for immediate shipment.  Call us, we are ready to help.
