Hey Craig, thanks for reaching out. Yes, the closet flange seal included in the Repair Kit # TH94MA is the same seal as the standalone Thetford Closet Flange Seal # TH43RA (Thetford part #33239). Thetford uses part #33239 as the replacement flange seal across a number of their RV toilets, including the Aqua-Magic Style II, and that's the seal included in the repair kit.

Since you've already confirmed your toilet uses the Thetford 42115 closet bolt kit, the # TH94MA kit is a good way to get the replacement bolts along with the correct 33239 flange seal in one package instead of buying them separately.
