33027 is a Thetford replacement blade seal designed for Aqua-Magic IV RV toilets. Installed in the toilet’s blade assembly, this seal helps maintain a proper seal when the flush blade is closed. It is intended for compatible Aqua-Magic IV high- and low-profile toilet models. This part is the blade seal only; it does not include the blade, track or other toilet components. Confirm your toilet model before ordering.
