## Description

Flush Ball Seal Kit for Dometic 310 Toilets

Review: Works great for a Dometic 310 - This seal was a perfect fit for my dometic 310 toilet in my RV. Installation was easy - the only potential issue is that you can't really feel when it is seated correctly, so I wasn't sure if it was really in place. I applied pressure all around to ensure it was in correctly. Once done I tested by adding some water to it. Where it would be gone in a matter of minutes now it has been holding for a few days. I didn't want to have to do this again any time soon, so I feel the extra cost for a OE part was worth it.
Review: Fit - Perfect fit and easy to install.

## Questions & Answers

**Q: Will this fit a Sealand 2010?**
A: No, this is NOT the proper seal for the 210 or 2010.  The proper seal for those models is the 385316140,

**Q: Will this fit a 300 series Dometic for RV?**
A: I purchased one for my 300 series toilet and it fit quite well. A little bit of massaging was needed to completely install but once situated, it worked fine

**Q: Is this an OEM dometic seal or 3rd party?**
A: Dometic thanks you for your question. This is a dometic seal. For further information, contact our support team at customersupportcenter@dometic.com.

**Q: Does this fit the Dometic 3400 electric model?**
A: Dometic thanks you for your question. Unfortunately, the 385311658 flush valve is only used on the 300 series toilets. We have verified with our RV sanitation department and there is not a 3400 model currently in production. Can you please verify your model number and contact us at customersupportcenter@dometic.com for more assistance?

### ⭐⭐⭐⭐⭐ Fit
*by N***M on November 2, 2025*

Perfect fit and easy to install.

### ⭐⭐⭐⭐⭐ A Good Seal That Works
*by D***E on August 22, 2025*

My trailer toilet would not hold water, it gradually leaked out, so I went the cheap route and purchased a two pack of non brand seals from Amazon. I really did a good job cleaning it all up and installed the new seal. The toilet leaked water quicker than with the original, old seal. I installed this seal in 2024 and it works perfectly with no leakage. To me it was on the expensive side, but it works like new so I recommend it. Don't waste your money on a cheap imitation like I did.
