Constructed from sponge material, this gasket compresses under bolt load to create a watertight seal that prevents leaks at the tank base. It measures 2.125 inches inner diameter, 3.25 inches outer diameter, and 1.1875 inches thick. Part of the Sioux Chief Series 490 line, it is a domestic-made component suited for plumbers and service techs replacing failed or deteriorated gaskets during toilet repair or tank replacement work.\u003c\/p\u003e\u003cp\u003eThis gasket is intended for close-couple toilet configurations where the tank mounts directly to the bowl. It is appropriate for residential bathroom plumbing service and is a common replacement item during toilet rebuilds, wax ring service calls, or any job requiring tank removal. The sponge construction allows it to conform to minor surface irregularities, maintaining a consistent seal under normal tank bolt torque.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSponge material conforms under compression for a consistent, leak-free seal\u003c\/li\u003e\n\u003cli\u003e2.125 inches ID x 3.25 inches OD x 1.1875 inches thick for close-couple fitment\u003c\/li\u003e\n\u003cli\u003ePart of the Series 490 gasket line\u003c\/li\u003e\n\u003cli\u003eDomestic manufacture\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement tank-to-bowl gasket for close-couple residential toilet configurations.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation is performed by a licensed plumber or qualified service technician.
