IGR3681 insulating gasket

The IGR3681 insulating gasket is specially designed for the RJ ring connection surface of the flange. It uses high-strength phenolic resin with insulating properties as the material and is processed into a gasket with an octagonal cross-section. It has a radial self-tightening sealing effect. It is in contact with the outside of the flange trapezoidal groove, and the sealing effect is achieved through bolt compression. The dimensions conform to the standard dimensions of ANSI, API, and PN flanges. It can also produce matching insulating gaskets according to the non-standard flange RJ sealing surface of the user's site.
