Ideal for homeowners and service professionals who want a reliable, long-lasting component that fits Filbur rectangular DE filters and preserves filtration efficiency over time. Why choose this Filbur grid? It’s engineered to keep filtration smooth and predictable. The extruded PVC center cores resist stress better than standard cores, while antimicrobial end caps protect against mold and odor in challenging water chemistry. The integrated fittings simplify installation, and the reinforced bands keep the grid aligned under pressure, delivering consistent debris capture and easier cleaning during routine maintenance. Use cases and scenarios:\n- Seasonal filter rebuilds where you need a trustworthy, OEM-grade DE grid that fits 18\" x 12-7\/16\" rectangular housings with an offset port.\n- Replacing worn or cracked grids to restore proper water clarity and filter efficiency without modifying the housing.\n- Upgrading from generic grids to Filbur’s design for improved durability in salt pools or high-chlorine environments. Practical tips:\n- Inspect the grid for cracks or deformation during routine maintenance and replace with FC-9875 if any weakness is detected.\n- Align the grid using the offset port—proper orientation is key to even DE distribution and optimal flow.\n- Clean and rinse the grid during service to prevent residue buildup that can impede filtration, then reinstall with attention to end-cap fittings for a leak-free seal. With the FC-9875 rectangular DE grid, you’re choosing a component engineered to maximize filtration efficiency, minimize downtime, and stand up to challenging pool chemistry—so you spend more time swimming and less time maintaining.\u003c\/div\u003e","brand":"Filbur Manufacturing","offers":[{"title":"Default Title","offer_id":40241552785450,"sku":"FC-9875","price":41.01,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0574\/4014\/1354\/products\/14-176-1135_xl.jpg?v=1769976123","url":"https:\/\/bathparts.com\/products\/filbur-rectangular-diatomaceous-earth-de-grid-for-pool-filters-18-inch-by-12-inch-offset-port-fc9875","provider":"Bath \u0026 Spa Superstore","version":"1.0","type":"link"}
