Details: Perfect replacement for your Kohler K-GP1059291 Canister Flush Valve Seal (red or yellow color). Made from high-quality, durable rubber. Equivalent to part K-GP1059291 / 2475620. Toilet gasket seals wear out over time and need to be replaced - replacement creates better flushing pressure and results in a quieter toilet. No one wants a loud or hard to flush toilet! Compatible with all Kohler toilets with a canister flush valve. If you have any questions about fit, please ask a question below. Outer diameter of 3 3/8". Please note: This is an aftermarket replacement product (produced by Impresa) meeting or exceeding the quality of OEM rings (based on in-house testing). Installation instructions for proper use below. Installation is simpler than you'd expect, and does not require you to remove the base of the toilet. Pack of 2 for a great value! Step 1: Turn off the water (at toilet's base). Step 2: Flush the toilet and ensure that the tank is fully empty (flush again if necessary). Step 3: Un-clip the flush chain. Step 4: Twist the stem counter-clockwise - this will require some force and you will hear a click. Step 5: Lift the flushing unit out from the toilet tank. Step 6: Replace the old seal with your new seal (only one seal per toilet). Step 7: Put the stem back in and twist clockwise to tighten. Step 8: Reinstall the flush chain. Step 9: Turn the water back on.
