You are using the correct part #34120 but the ball seal will NOT fit the Aqua Magic II. This ball valve seal is 4-3/4" in diameter and will not fit the plastic ring at the bottom the toilet. The correct ball valve seal is 4-1/4 inch in diameter. Get Revain's OEM Thetford Gasket Kit with the same part #34120 for $20. This seller was great and refunded the purchase price immediately with no problems.
