Octagonal

Seaco manufactures and supplies a large variety of ring joint gaskets. The RTJ standard size gaskets are manufactured in accordance to API-6A and ASME B16.20 specifications. Total control of manufacturing processes ensures correct gasket surface and hardness to give a good seal without damaging flange connections.The hardness of the ring should always be less than the hardness of the flanges to prevent flange deformation. The sealing surfaces on the ring joint grooves must be smoothly finished to 63 micro inches.

Octagonal and Oval configurations are interchangeable on flatbottomed groove flanges that have a 23° angle groove wall.
