The kit includes a 16-inch magnesium anode rod paired with a 5-inch dielectric heat trap (DHT) nipple, making it a complete assembly for direct installation. Magnesium anode rods work through sacrificial electrochemical action, corroding in place of the steel tank lining. This extends tank service life and is a standard maintenance component replaced by licensed plumbers during routine water heater servicing.\u003c\/p\u003e\u003cp\u003eThis anode rod kit is suited for residential storage-type water heater applications where the existing anode rod has depleted or when a water heater is being serviced for odor, reduced efficiency, or as part of a preventive maintenance schedule. The included DHT nipple simplifies the installation by combining the anode rod and heat trap nipple into a single serviceable unit, reducing overall labor time during replacement.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eMagnesium construction provides effective sacrificial corrosion protection for steel water heater tanks\u003c\/li\u003e\n\u003cli\u003e16-inch rod length suitable for standard residential water heater configurations\u003c\/li\u003e\n\u003cli\u003eIncludes 5-inch DHT nipple for integrated heat trap functionality\u003c\/li\u003e\n\u003cli\u003eNipple-style end type allows straightforward threaded installation\u003c\/li\u003e\n\u003cli\u003eOEM replacement part designed to restore factory-level tank protection\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement anode rod kit for residential storage water heaters requiring a 16-inch magnesium anode with a DHT nipple assembly.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber. Before servicing, shut off the cold water supply and power or gas to the water heater, and relieve tank pressure at a hot water faucet. A socket wrench with a 1-1\/16-inch socket is typically required to remove and install the anode rod. Follow all applicable local plumbing codes and manufacturer guidelines during replacement.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 16 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnd Type\u003c\/strong\u003e: Nipple\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDHT Nipple Length\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Magnesium\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eApplication\u003c\/strong\u003e: Replacement Part\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: AO SMITH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 100300397\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"TAILWIND","offers":[{"title":"Default Title","offer_id":51149710229810,"sku":"100300397","price":76.18,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/305990146.jpg?v=1778599992","url":"https:\/\/voomisupply.com\/products\/ao-smith-100300397-magnesium-anode-rod-kit-16-in-dht-nipple","provider":"Voomi Supply","version":"1.0","type":"link"}
