2 Inch Gasket for Western Pottery tank to bowl. Fits all old style bowls and tanks. Two inch on both sides. This fits the hexagon (6 sided) nut. This is an Original Equipment Manufacturer (OEM) part specifically for Western Pottery toilets.
Note: There are two ways to confirm you are ordering the correct part: 1) lift the flapper and measure the hole, if is 2 inches this is the correct part. 2) remove the tank, if the nut has 6 sides this is the correct part. The hexagon impression will be formed by the weight of the tank on the gasket.
