Still, it is typically recommended to replace your o-ring on every third filter change to ensure it is in top shape to prevent leaks. **Q: Can I use grease or lubricant on these o-rings?** A: You can if you'd like to. Generally a brand new buna-n o-ring can be installed just with wetting it with water. However, these o-rings are compatible with all silicone and petroleum based lubricants, as well as natural oils like vegetable oil. **Q: What if I don't know what o-ring part number my filter housing needs?** A: Use our handy printable water filter housing o-ring size chart. Print out the chart and lay your old o-ring on the page to see which o-ring it matches with. You can find the size chart listed as "User Guide [PDF]" under "Product guides and documents" **Q: Are these o-rings safe for use in my drinking water?** A: Yes! These Captain O-Ring replacement o-rings are molded from NSF 61 certified buna-n rubber for safe and clean drinking water. **Q: Where is this o-ring kit assembled?** A: Proudly assembled in the USA! We hand assemble these kits in Gloucester City, New Jersey. ## Frequently Bought Together - Captain O-Ring - Replacement 63597174C / 63597174P / AO-WH-STD-OR-2 / WP252235 Orings for 3M Aqua-Pure, AO Smith, Watts Filter Housings (3 Pack) - 3M Aqua-Pure AP110 2-Pack Whole House Replacement Water Filter Cartridges, 5 Micron Sediment Reduction, for use with AP11T or AP101T Housing - 3M Aqua-Pure AP101T Whole House Transparent Water Filter Housing, Ideal for 1-2 Bath Homes, Standard 1-high Drop-in Cartridge --- ## 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.no/products/15716247-captain-o-ring-replacement-63597174c-63597174p-ao-wh-std-2](https://www.desertcart.no/products/15716247-captain-o-ring-replacement-63597174c-63597174p-ao-wh-std-2) --- *Product available on Desertcart Norway* *Store origin: NO* *Last updated: 2026-09-17*
