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? ## Frequently Bought Together - Dometic 385311658 Flush Ball Seal Kit 310 Toilets - Dometic 385311641 Genuine OEM Water Valve Kit | 300 301 310 320 Dometic and Sealand Toilets | Includes Hose Clamp and Fasteners | White Compact Kit for Efficient Repair and Replacement - Dometic 385311652 Mounting Hardware Kit, White --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/16544448-dometic-genuine-oem-flush-ball-seal-kit-385311658-for-300](https://www.desertcart.hr/products/16544448-dometic-genuine-oem-flush-ball-seal-kit-385311658-for-300) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-25*
