This type of element threads directly into a tank or vessel fitting, providing resistive heat transfer to a liquid medium such as water. It is a common replacement component in electric water heaters, small storage tanks, and similar hydronic or process heating applications. Installation is typically performed by a licensed plumber or HVAC technician during routine maintenance or equipment servicing.\u003c\/p\u003e\u003cp\u003eThis screw plug heating element is suited for residential and light commercial electric water heating systems where a 1500-watt, 120-volt element is specified. The screw plug design allows for direct threaded installation into standard element ports, making it a straightforward field replacement. Consult the equipment nameplate and OEM documentation to confirm wattage, voltage, and thread specification before installation.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e1500-watt resistive heating output at 120 volts\u003c\/li\u003e\n\u003cli\u003eScrew plug configuration for threaded tank or vessel installation\u003c\/li\u003e\n\u003cli\u003eDesigned as a direct replacement immersion element\u003c\/li\u003e\n\u003cli\u003eCompact form factor suited to standard element port fittings\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement screw plug immersion heating element for electric water heaters and storage tanks requiring a 1500-watt, 120-volt screw plug element.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed plumber or qualified technician. Shut off electrical power at the breaker and close the cold water supply valve before removing or installing the element. Drain the tank to below the element port level before unthreading the old element. Ensure proper thread engagement and use an appropriate element wrench to avoid cross-threading or over-tightening the screw plug fitting.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWattage\u003c\/strong\u003e: 1500 watts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 120 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElement Type\u003c\/strong\u003e: Screw Plug Immersion\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: KNOX SALES COMPANY\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 481000\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"KNOX SALES COMPANY","offers":[{"title":"Default Title","offer_id":51233806254386,"sku":"481000","price":18.45,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307615183.jpg?v=1780109516","url":"https:\/\/voomisupply.com\/products\/knox-sales-company-481000-screw-plug-heating-element","provider":"Voomi Supply","version":"1.0","type":"link"}
