{"product_id":"pentair-white-pvc-bulkhead-adapter-nut","title":"Pentair White PVC Bulkhead Adapter Nut","description":"\u003cp\u003eThe Pentair White PVC Bulkhead Adapter Nut (Product #: 274407Z \/ 274407) is a vital, factory-original OEM replacement hardware component designed to establish rigid, leak-free plumbing connections on a wide array of pool and spa filtration systems. Manufactured by Pentair (formerly PacFab \/ Purex), this precision-threaded female union collar serves as the mechanical anchoring interface that locks standard 2-inch or 1.5-inch external plumbing connector configurations tightly onto the integrated bulkhead ports of Triton® II sand filters, Sea Horse® stainless steel cartridge filters, and specialized HiFlow™ top-mount and side-mount clamp-on multiport backwash valves (including models 261049, 261050, and 261142). Injection-molded from a premium, high-density white polyvinyl chloride (PVC) engineering compound, this heavy-duty retaining collar provides complete immunity to chemical degradation from high chlorine or bromine concentrations, resists mineral scale buildup, and features structural UV stabilizers to eliminate brittleness and cracking under constant outdoor weathering and high-temperature pool pad environments. Measuring approximately 4.25 inches in outer diameter by 1.125 inches in width, the collar boasts deep, molded exterior ribs that provide maximum manual grip torque during installation, allowing technicians or homeowners to hand-tighten the coupling to compress the internal sealing o-rings without stripping the threads or requiring specialized plumbing wrenches. By absorbing the continuous hydraulic vibration and line pressures generated by powerful circulation pumps up to a maximum rating of 50 PSI, this adapter nut prevents costly pressure-side water leaks and catastrophic suction-side air induction. \u003cspan class=\"citation-58\"\u003eThe physical weight of this single Pentair White PVC Bulkhead Adapter Nut is exceptionally light at approximately \u003c\/span\u003e\u003cb data-path-to-node=\"1\" data-index-in-node=\"1858\"\u003e\u003cspan class=\"citation-58\"\u003e0.16 pounds\u003c\/span\u003e\u003c\/b\u003e\u003cspan class=\"citation-58 citation-end-58\"\u003e (roughly 2.56 ounces, with a packaged shipping weight of approximately 0.2 pounds), providing pool professionals and residential managers with an incredibly strong, featherweight, and indispensable hardware component for flawless water circulation loops.\u003csup class=\"superscript\" data-turn-source-index=\"1\"\u003e\u003c!----\u003e\u003c\/sup\u003e\u003c\/span\u003e\u003c\/p\u003e","brand":"Commercial Pool and Spa Supplies","offers":[{"title":"Default Title","offer_id":53165466550383,"sku":"274407Z","price":30.6,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0678\/3785\/3807\/files\/274407-nutadapter-top.png?v=1779894737","url":"https:\/\/commercialpoolandspasupplies.com\/products\/pentair-white-pvc-bulkhead-adapter-nut","provider":"Commercial Pool and Spa Supplies ","version":"1.0","type":"link"}
