Description
Overview
The iFJF 385311462 RV Toilet Rubber Bowl Leak Seal Kit is the permanent fix for that annoying toilet bowl leak that wastes water and creates unpleasant odors in your RV. If your toilet bowl won't hold water between flushes or you smell sewer gas seeping through, this seal kit replaces both the rubber bowl seal and flush ball seal — restoring a watertight barrier without expensive shop visits.
Compatible with most popular Dometic/SeaLand pedal-flush and Vac-UFlush toilet models (see compatibility chart below). Built from high-quality sealing rubber that matches or exceeds OEM material specs. No special tools required — most RV owners complete the swap in under 15 minutes.
Key Features
-
Dual-Seal Design — Includes both rubber bowl seal (7" x 2" x 1/16") and flush ball seal (7" x 1-5/8" x 1/4") for a complete leak solution in one kit.
-
Watertight Shutoff — Precision-molded rubber creates a tight seal against the water outlet pipe, stopping the slow drain-down that wastes fresh water between flushes.
-
Odor Elimination — Blocks sewer gas from entering the RV interior through a leaking toilet seal.
-
15-Minute DIY Install — Simple plug-and-play replacement with no special tools or plumbing skills required. Saves $100+ in dealer labor fees.
-
OEM-Spec Rubber — Manufactured from durable, flexible rubber compound that resists cracking, hardening, and chemical breakdown from RV holding tank treatments.

Frequently Asked Questions
Q: How do I know if my toilet bowl seal is leaking?
A: The #1 symptom is the toilet bowl losing water between flushes. If you fill the bowl, walk away, and come back to find it nearly empty, the bowl seal is failing. You may also notice a faint sewer odor around the toilet area.
Q: Will this fit my Dometic 310 toilet?
A: No. This seal kit is NOT compatible with Dometic 300, 310, or 320 series toilets. It is designed for the older pedal-flush model numbers listed in the compatibility chart. Check the model number sticker inside your toilet before ordering.
Q: How long does installation take?
A: Most RV owners complete the swap in 15 minutes with basic hand tools (screwdriver and wrench). No plumbing skills needed.
Q: Does this kit include both seals I need?
A: Yes. The package includes one rubber bowl seal and one rubber flush ball seal. Replacing both at once ensures a complete, long-lasting fix.
Q: What's your warranty?
A: All iFJF products come with a 12-month warranty against manufacturing defects. Contact us for a free replacement or full refund.
