If your RV toilet is leaking, dripping into the bowl between flushes, or the flush ball no longer seats cleanly, the ball seal is almost always the culprit. This Lippert factory-matched replacement seal restores a watertight fit to your Flow Max toilet in minutes -- no special tools, no plumber required.
The ball seal is the rubber ring that surrounds the flush ball inside your RV toilet. Over time, exposure to holding tank chemicals, UV light, and repeated mechanical cycling causes the seal to harden, crack, or deform. Once it loses its shape, water slowly seeps past the ball and into the bowl -- or worse, odors migrate back into the coach.
Lippert part number 2023038024 is the correct replacement for Flow Max toilets. It matches the original dimensions exactly (4.02" OD x 2.76" ID) and is made from a black elastomeric compound designed to resist the chemicals commonly used in RV black tanks.
4.02" outer diameter and 2.76" inner diameter match the original Flow Max flush ball seat precisely -- no trimming or stretching required.
Black elastomeric construction resists common RV holding tank treatments, deodorizers, and drop-in tablets that can degrade generic seals faster.
Weighs only 0.05 lbs. The seal seats without adhesives and can typically be replaced without removing the toilet from its base.
Backed by Lippert's limited 1-year manufacturer warranty against defects in materials and workmanship.
Most RV toilet ball seals last several years under normal use, but replacement is due when you notice any of these signs:
While this part is listed for Lippert Flow Max toilets, it will also fit any RV toilet that uses a ball seal measuring 4.02" OD x 2.76" ID. If your existing seal matches those dimensions, this part will work regardless of the toilet brand. Measure your old seal or check your toilet's parts diagram before ordering if you are unsure.
Replacing the ball seal on a Flow Max toilet is a straightforward repair:
