Even though it's not totally necessary they should be replaced to avoid having to tighten the filter housing more than is needed with new o rings. These are new o rings and work well. --- ## 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.be/products/400418438-express-water-whole-house-o-ring-replacement-kit-5-5](https://www.desertcart.be/products/400418438-express-water-whole-house-o-ring-replacement-kit-5-5) --- *Product available on Desertcart Belgium* *Store origin: BE* *Last updated: 2026-08-14*
