boeemi RV toilet seal kit — Thetford Aqua Magic drive arm 42048 & flange seal 33239, stops leaks, easy DIY fit

This boeemi RV Toilet Seal Kit replaces the waste ball drive arm (42048/42209) and closet flange seal (33239) to stop common leaks and restore reliable bowl closure on Thetford Aqua Magic toilets.

If your RV toilet is dripping or not sealing properly, this repair kit supplies the two core parts that commonly wear out: the drive arm that moves the waste ball and the flange seal that seals the bowl to the waste outlet. Designed to match Thetford Aqua Magic Style II, Lite, Plus and Residence models, the kit contains the drive arm and flange seal plus the small fittings needed for installation. It does not include the waste ball, pedal assembly, or model numbers 34117 and 42072 parts.

How will this kit stop leaks in my RV toilet?

Worn or cracked seals and a weakened drive arm allow water to bypass the closure, causing slow leaks or continuous dripping. Replacing the flange seal restores a tight connection at the bowl outlet while the new drive arm ensures smooth, complete travel of the waste ball.

• Includes closet flange seal 33239 to reseal bowl outlet.
• Includes waste ball drive arm 42048/42209 for reliable movement.
• Replaces common wear points that cause seepage or slow drains.
• Helps restore full holding power without replacing the entire toilet.

What toilet models and setups is this compatible with?

The components were engineered for Thetford’s Aqua Magic lineup—Style II, Lite, Plus and Residence—found in many RVs and trailers. Before ordering, confirm your toilet’s part numbers and configuration; this kit fits the drive-arm and flange seal roles, not the waste ball or pedal assembly.

• Specifically fits Aqua Magic Style II, Lite, Plus, Residence models.
• Not compatible if your unit requires parts 34117 or 42072.
• Check existing part numbers on removal for a snug fit.
• Works for most common RV plastic bowl assemblies of these models.

How difficult is installation and what tools or supplies are recommended?

Installation is a straightforward DIY weekend job for a basic toolbox user. You’ll need simple hand tools and a bit of plumber’s grease to help seat the new rubber seal; follow basic disassembly steps to access the flange and drive arm.

• Requires basic tools: screwdriver, pliers, possibly a socket set.
• Use plumber’s grease on the new seal for proper seating and easier fit.
• Turn off water and empty bowl before starting to avoid spills.
• Allow 30–90 minutes depending on access and experience.

What is included and what is not included in the kit?

The package contains the waste ball drive arm (42048/42209), the closet flange seal (33239), and the necessary small hardware for replacing those items. It does not contain the waste ball, foot pedal mechanism, or unrelated part numbers listed elsewhere.
