Ever!! *by on Reviewed in the United States 3 August 2026* Finally a pool filter basket O-ring that actually seals correctly! I suppose because the provider specified " made in the USA"!I've bought these before from other vendors and frankly they appeared to be undersizeddiameter-wise of the rubber o-ring! These are somewhat thicker and sealed the basket air-tight, no bubbles in the pool or the filter basket and you don't have to compress the o-ring down ridiculously so the O-ring dies it's job just hand tight, not hammer tight and the pump primed immediately! 💯🥇the clear winner in this item category! ### ⭐⭐⭐⭐⭐ The O-rings fit my strainer lid *by on Reviewed in the United States 1 August 2026* The o-rings fit perfectly. It is also nice to knowI now have spares on hand when needed. ### ⭐⭐⭐⭐⭐ Fits pentair whisper *by on Reviewed in the United States 8 August 2026* Fits my Pentair filter --- ## 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.com.kw/products/331678751-captain-o-ring-llc-replacement-for-pentek-pentair-350013-o](https://www.desertcart.com.kw/products/331678751-captain-o-ring-llc-replacement-for-pentek-pentair-350013-o) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-10-16*
