TOVEN-RV RV Toilet Water Valve Kit & Flush Ball Seal — Fits Dometic 300–321, Sealand, Traveler, Vacuflush

Keep your RV toilet flushing reliably with the TOVEN-RV RV Toilet Water Valve Kit and Flush Ball Seal. This kit is designed to replace the official parts 385311641 and 385311658 while maintaining compatibility with a broad range of pedal-flush toilets used in RVs, including Dometic 300, 301, 310, 311, 320, and 321 series. It also works with many Sealand, Traveler, and Vacuflush toilets, so you can source a single solution for multiple units across your fleet.

Durability you can feel in the field. The valve body is crafted from reinforced ABS and fused with ultrasonic welding at the joints, delivering a solid feel and improved resistance to cracking in cold weather. When parked in winter or exposed to freezing temperatures, this design is built to hold up and reduce common failure points that can lead to leaks. While it is not a guarantee of weatherproof performance in every climate, the construction is aimed at longer-term reliability through harsh conditions.

Inside the kit, you’ll find a precision-engineered valve paired with heavy-duty seals. This combination is designed to keep water pressure steady and cut down on running after a flush—an issue many RV users want to avoid. The stainless steel mesh filter is integrated to trap debris before it reaches the valve, helping maintain smooth operation and reduce blockages over time.
