Forged from high-grade, marine-strength brass alloy, this corrosion-resistant wing nut is designed to survive constant submersion in chemically treated, high-pressure pool water without scaling, rusting, or binding. It threads directly onto the top of the internal 1\/4-inch vertical tie rod, serving as the final anchoring point that manually compresses the upper plastic manifold down against the internal filter grids. This tool-free, hand-tightened compression secures the entire internal grid core into a completely rigid, parallel matrix, preventing structural shifting or internal water bypass during intense pump filtration or high-velocity backwash cycles. Because it is a compact hardware element, the kit has an ultra-light \u003cb data-path-to-node=\"0\" data-index-in-node=\"1032\"\u003eactual product weight of roughly 0.05 to 0.10 pounds\u003c\/b\u003e (under 2 ounces), and ships in padded small-parts envelopes or miniature boxes with a \u003cb data-path-to-node=\"0\" data-index-in-node=\"1171\"\u003epackaged shipping weight of approximately 0.20 to 0.30 pounds\u003c\/b\u003e to protect the precision-cut internal threads during transit.\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53762640707695,"sku":"35402-0074Z","price":27.0,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/pentair-nut-wing-kit-25-20-35402-0074z-pool-filter-parts-4956743_1800x1800_449b20ec-c3ec-4b18-aa55-04949b2e298e.jpg?v=1783609270","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-25-20-brass-wing-nut-kit","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
