## Description

The Thetford 33027 Blade Seal is structured and precisely manufactured through a series of careful processes and to promote the benefits of quality and excellence in performance. Exclusively manufactured for complete compatibility with Thetford Aqua-Magic IV High and Low Hand Flush RV toilet units. This high-grade replacement part delivers enhanced functionality to every component of toilet units, ensuring each part offers maximized performance.

Review: I bought a used Sprinter van, and the toilet smelled to high heaven. Part of the problem was that the toilet seal would not hold water in the bowl. I took it into a RV service center and they wanted $96.00 to replace it. I searched on google and it took a guy 5 minutes to replace the seal. I did it myself in about 10 minutes. No special tools needed. I tied a string to the seal to prevent me from dropping it in the toilet during the replacement. Glad I did.
Review: This seal was very easy to install as I had already removed the toilet to replace the flooring, so it was installed from the bottom. I removed the old one and just slipped on the new one then lubed with a silicone grease. After re installing the toilet the first few times the flapper was a bit stiff to open but now works great and holds water in the bowl. Happy DW.
