I have had no issues with them and they are working as they should. ### ⭐⭐⭐⭐⭐ Review *by T***H on 4 January 2020* Worked well - saved our softener from the trash heap. ### ⭐⭐⭐⭐⭐ Review *by A***R on 6 October 2020* Fit just like they should and very easy to replace. Unfortunately I discovered I needed the bypass valve itself and had to go back online and buy that. apparently the plastic edges of the bypass valve were chipped and that's why it was leaking so I recommend you just go ahead and buy the bypass valve assembly. --- ## 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.pt/products/329250055-captain-o-ring-water-softener-seal-kit-4-pack-part](https://www.desertcart.pt/products/329250055-captain-o-ring-water-softener-seal-kit-4-pack-part) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-04-23*
