I had zero issues with this product. If you are still getting leaks after install 1) make sure you installed correctly 2) read the Dometic toilet instructions or google instructions for new seals on Dometic toilet. There are some additional steps you can take to make sure it seals properly. Any new seal may need to be softened to mold to ball closure underneath. Follow Dometic instructions for this. It is a small paragrah in the instruction booklet. Advise buying rv toilet seal conditioner and lube as well to help with this.

I recently replaced the toilet seal on my Dometic 300 series toilet with this gasket kit, and it has made a world of difference! The installation was straightforward, thanks to the clear instructions and the perfect fit. The quality of the gasket is top-notch, providing a tight seal that prevents any leaks, ensuring everything stays clean and dry. This kit is a great value, saving me time and hassle compared to other options I’ve tried. Since replacing the seal, the toilet operates smoothly without any issues. I highly recommend this replacement kit to anyone with a Dometic 300, 310, or 320 toilet. It’s durable, easy to install, and a must-have for maintaining your RV’s bathroom!
