Customer Questions & Answers

Does it fit to k4620 tank to bowl 4276?

Asked by: NAR
By the way, if you get the GP51487 kit, there's a couple of things Kohler conveniently left out of it - 1) GP50751 - the large white plastic nut which attaches the gasket to the bowl. 2) GP50752 - the white washer that goes with the gasket and nut above. You might also want to get another tank seal #1145626 that goes on the flush valve. I have the same toilet tank K4620, but I'm getting the Flush Valve Kit #85406, which includes everything needed (including 50751, 50752, and 1145626), except for the bolts (GP52050). Have Fun!!

Asked by: Cooper
Hi Cooper, my name is Sarah with KOHLER Co. I am glad to answer your question. This toilet does not require a tank to bowl gasket as it is a one piece toilet. The anchor kit needed for the toilet seat attachment is part number 84999. If you have any questions, please contact us directly at 1-800-456-4537. Thank you for choosing KOHLER.
