{"product_id":"pentair-10-24-stainless-steel-serrated-flange-nut","title":"Pentair #10-24 Stainless Steel Serrated Flange Nut","description":"\u003cp\u003eThe Pentair #10-24 Stainless Steel Serrated Flange Nut (Product #: 273510 \/ 27-3510) is a factory-original OEM replacement fastening component engineered to maintain precise structural compression and vibrational resistance across pool and spa backwash filtration networks. Specifically utilized to securely lock down the upper dome cover and indexing assemblies of Pentair, PacFab, and Praher 1.5-inch and 2-inch multiport valves—which are commonly paired with Triton® II sand filters and FNS® Plus or Quad D.E.® vertical grid separation tanks—this specialized hardware element ensures a unified mechanical clamp over the valve body. Forged from a premium, high-tensile 18-8 grade stainless steel alloy, the nut features an integrated, wide-diameter bottom flange equipped with directional locking serrations. When torqued down onto its mating standard #10-24 machine bolts, these teeth bite directly into the polymer housing surface, acting as an integrated lock washer that prevents the nut from backing off under heavy hydraulic surges or continuous motor vibrations. This non-binding metallic composition provides complete immunity to atmospheric rust, pump room humidity, and concentrated pool sanitizers under system operating pressures up to 50 PSI, effectively safeguarding against pressure-side water weeping or suction-side air induction.
