It seems that pouring in just enough to completely cover the bottom of the bowl would lube it.** A: I'm sorry to say this stuff was garbage. It was easier to just go buy a new seal than to waste the $ on this. Didn't even work a little bit. **Q: do i pour in while the toilet has water in it or should the seal be dry?** A: Pour in with no water. Make sure valve is closed. Pour about a 1/4 of container if I remember correctly and leave overnight. Fixed my seal. Hasn't leaked since **Q: Can it be used with valve lube or is this the same thing** A: The two products are compatible with one another and serve two different purposes. Toilet seal works in the bowl to keep the flush valve functioning . Valve lube goes straight into the blackwater (poo) tank and ALSO in the greywater (sink&shower) tank to prevent problems with the seals that keep the drain valves operational. I use both as preventive maintenance. **Q: Does this work for the seal on cassette toilets?** A: This is not a sealant. It is simply advertised as a lubricant for sliding toilet parts. If you're using it as such....it should work ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by W***R on February 7, 2026* ### ⭐⭐⭐⭐⭐ Review *by D***N on March 17, 2026* ### ⭐⭐⭐⭐⭐ Review *by D***N on December 16, 2025* ## Frequently Bought Together - Thetford RV Toilet Seal Lube and Conditioner - Toilet Seal Lubricant - 24 oz 36663 - Liquified RV Toilet Treatment - Black Holding Tank Digester - Odor Eliminator - Orange Scent - Matts RV Reviews (Orange, 32oz) - Camco Tastepure RV Water Filter - New & Advanced RV Inline Water Filter with Flexible Hose Protector - GAC & KDF Filtration - Made in USA - Camping Essentials for Fresh Drinking Water (40043) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vn/products/11222443-rv-toilet-seal-lube-and-conditioner-toilet-seal-lubricant-24](https://www.desertcart.vn/products/11222443-rv-toilet-seal-lube-and-conditioner-toilet-seal-lubricant-24) --- *Product available on Desertcart Vietnam* *Store origin: VN* *Last updated: 2026-05-15*
