Much less expensive then the name brand. I would buy them again! ### ⭐⭐⭐⭐⭐ These worked Great! *by P***L on March 31, 2021* These duck bills where easy to install and worked as expected ### ⭐ These are inexpensive for a reason *by L***T on June 24, 2024* Such a simple thing and you’d think it’s just a rubber valve. But, the compound they use to make these doesn’t work. I’ve installed these valves multiple times, on rebuild after rebuild, thinking that these are ok. But they’re not. They’ll perform okay for about a month and then they start to harden causing the pump to have extended run time trying to build pressure, then the pump will trigger from pressure loss randomly, and then before you know it you’re turning the system on and off between uses. Well, I replaced seals, pump housings pieces, bellows, vacuum switches, etc. and like a good boy I replaced these valves every time I opened the system, not realizing that these cheap valves have been the issue the whole time. The system would be fine for a little while and then start acting up after a couple weeks. The price of the OE valves is crazy expensive and kept me from buying them, but they have now lasted me 8-9 times longer than these cheap valves. And I don’t know about you but cracking open our vacuum flush system is not on my top ten things to do in life. So, bite the bullet and get the OE. ## Frequently Bought Together - TycoonWon 2 Pair 385310076 Duckbill Valve Kit Replacement for Sealand Vacuum Generators S115A, S12, 52A, S32, T12, T24, and T32 Pump,1-1/2" - DOMETIC 385230980 Pump Bellow Kit White ‎9.09 x 5.39 x 4.09 inches - Dometic 385310151 O-Ring Kit --- ## 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.co.uk/products/179501269-4-pack-1-1-2-385310076-duckbill-valve-kit-replacement](https://www.desertcart.co.uk/products/179501269-4-pack-1-1-2-385310076-duckbill-valve-kit-replacement) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-25*
