This heavy-duty grid matrix is standard hardware across Pentair Clean \u0026amp; Clear Plus cartridge filters spanning the 320, 420, and 520 square foot models (CCP320, CCP420, and CCP520), as well as Pentair Quad D.E. 60, 80, and 100 filtration vessels.\u003c\/p\u003e\n\u003cp data-path-to-node=\"1\"\u003eInjection-molded from a thick-walled, high-impact, and chemically inert polymer composite, this circular manifold functions as the centralized upper stabilizer for the entire internal grid core. Its primary operational role is to simultaneously align, balance, and lock the four large vertical cartridge elements into a perfectly rigid, uniform cluster configuration. By holding the tops of the elements firmly in position, it prevents the individual cartridges from shifting, tilting, or buckling under the intense crushing force generated by high-velocity pool water circulation.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eThe underside of the manifold features four precision-molded socket seats that seal tightly over the upper openings of the filter cartridges, forcing all incoming pressurized water to pass through the exterior fabric pleats rather than bypassing the media core. The center of the manifold is designed with a direct slip-fit connection that anchors onto the main vertical internal standpipe, channeling the combined streams of clean, debris-free water downward into the filter's lower bulkhead and back out to the pool return plumbing. Additionally, it features an integrated holding track for the automated internal air bleed tube assembly, allowing pocketed air to rise cleanly to the top of the tank dome for safe evacuation.\u003c\/p\u003e\n\u003cp data-path-to-node=\"3\"\u003eThis robust structural framework enables the internal manifold to manage massive fluid velocities and safely sustain continuous system operating pressures up to 50 PSI without warping, cracking, or experiencing hydraulic bypass under heavy pump vibration surges. Engineered to remain permanently submerged in a highly dynamic, chemical-laden framework, its rugged composite design completely resists material degradation, stress-cracking, and bleaching from exposure to high-strength pool sanitizers like chlorine, bromine, and routine winterizing acid washes. Due to its wide-diameter, four-port solid plastic structural layout, this individual top manifold carries a net product and shipping weight of approximately \u003cb data-path-to-node=\"3\" data-index-in-node=\"718\"\u003e2.40 to 3.00 pounds\u003c\/b\u003e.\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53416217641071,"sku":"170027","price":137.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/170027__12515.jpg?v=1782745747","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-320-420-520-sqft-clean-clear-plus-top-manifold","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
