LAMONS STYLE-388 OCTAGONAL RING JOINT GASKET

GP&S Enterprises, LLC proudly offers Lamons API Ring Joint Gaskets, which come in two basic types of either an oval cross section or an octagonal cross section.  These basic shape gaskets are used in pressures up to 5000 psi.  The dimensions are standardized and require specially grooved flanges.  The octagonal cross section has a higher sealing efficiency than the oval and would be the preferred gasket.  However, only the oval cross section can be used in the old type round bottom groove.  The newer flat bottom groove design will accept either the oval or the octagonal cross section.  The sealing surfaces on the ring joint grooves must be smoothly finished to 63 micro-inches.  The hardness of the ring should always be less than the hardness of the flanges.
