This structural hub serves as the central plumbing foundation across Pentair’s premier product lines—including the FNS Plus Diatomaceous Earth (D.E.) series, Clean \u0026amp; Clear Plus multi-cartridge filters, and Triton II high-rate sand vessels—where its perimeter features precision-machined receiving sockets designed to securely anchor the lower necks of vertical D.E. grids, cartridge elements, or lateral arms. Its primary operational role is to act as the central extraction hub at the lowest pressure point of the filter tank; during the standard filtration cycle, clean, purified water that has passed through the filtering media drains into these radial ports, where the hub consolidates the individual fluid streams and channels them cleanly into the vertical standpipe or out through the bottom tank bulkhead. This organized hydraulic path maximizes flow efficiency while minimizing system back-pressure, allowing the internal plumbing core to safely handle massive water circulation velocities and sustain continuous internal operating pressures up to 50 PSI without warping, leaking, or cracking under sudden pump startup surges or high-velocity backwash flow reversals. Built to remain permanently submerged beneath the heavy weight of dense sand or saturated filter elements, its rugged composite matrix completely resists material softening, structural deformation, and corrosive breakdown from continuous exposure to high-strength pool sanitizers like chlorine, bromine, or routine scale-remover acid flushes. Due to its rigid, multi-port plastic configuration and thick-walled central socket reinforcement, this replacement collector hub assembly carries a net product and shipping weight of approximately \u003cb data-path-to-node=\"0\" data-index-in-node=\"2030\"\u003e1.50 to 2.25 pounds\u003c\/b\u003e (about 24.0 to 36.0 ounces).\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c!----\u003e\n\u003c\/div\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53416248574063,"sku":"WC137-519P","price":103.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/200044_8e1b9c88-59fa-403d-8fb1-3453d849e61c.webp?v=1782747677","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-collector-hub-assembly","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
