Description
Product Overview
The AOMUCH 33239 toilet flange seal is engineered for RV, camper and trailer toilet systems. Crafted from a proprietary high‑performance rubber blend, the seal offers superior elasticity and resistance to chemicals found in black water. Measuring 4.72 x 0.75 x 4.72 inches and weighing just 1.87 ounces, it provides a compact yet robust solution. The design fits standard 3″ toilet flanges, replacing part numbers such as 02125, Aqua Magic Galaxy, Starlite, Aqua Magic V, and Bravura models. Its upgraded geometry creates a tighter grip on the pipe, minimizing the risk of leaks during travel.
Usage
This seal is ideal for RV owners, mobile homeowners, and anyone with a portable sanitation system. Install it when replacing a worn flange or during routine maintenance of your black water tank connections. It performs reliably in a range of temperatures and vibrations typical of road travel, making it perfect for long trips, weekend getaways, and full‑time van life.
