This replacement lid is designed to fit the larger-capacity, single-element Pentair Clean \u0026amp; Clear 150-square-foot and 200-square-foot filter models (specifically CC150 and CC200).\u003c\/p\u003e\n\u003cp data-path-to-node=\"1\"\u003eInjection-molded from a thick-walled, glass-reinforced engineering polymer composite, this circular dome serves as the primary structural cap for the pressurized filter vessel. Its primary operational role is to completely enclose the upper tank chamber, seating tightly over the main body O-ring directly beneath the heavy-duty metal tension clamp or locking ring assembly. By establishing a uniform, highly secure compression boundary around the center perimeter of the filter, it ensures the vessel can safely contain its high-efficiency hydraulic flow path while sustaining continuous internal system operating pressures up to 50 PSI without weeping, flexing, or risking structural lid separation under sudden pump startup surges.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eThe apex of the dome features integrated, precision-molded interface ports designed to house the external system pressure gauge and the manual High Flow™ air relief valve assembly. This positioning allows pool operators to cleanly bleed trapped air pockets from the absolute highest point of the tank core during routine maintenance and filtration start-up cycles. Engineered to withstand decades of demanding outdoor equipment pad weathering, direct UV exposure, and intense seasonal temperature shifts, its robust composite framework completely resists material structural degradation, stress-cracking, and chemical bleaching from direct contact with highly concentrated pool sanitizers like chlorine, bromine, and salt-chlorine generator outputs. Due to its wide-diameter, thick-gauge reinforced plastic structural profile, this individual replacement tank lid carries a net product and shipping weight of approximately \u003cb data-path-to-node=\"2\" data-index-in-node=\"923\"\u003e5.40 to 6.20 pounds\u003c\/b\u003e.\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53416217247855,"sku":"178546Z","price":274.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/178561__14281_c6be906e-3f47-4d21-811b-950db7a06b5f.jpg?v=1782745695","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-150-and-200-sqft-clean-clear-tank-lid","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
