It is machined from bronze for corrosion resistance in a marine environment and features a 2 inch diameter body with a 1\/2 inch NPT thread size, allowing it to thread into a matching garboard drain fitting or hull opening. The plug is installed and removed with a standard #8 flat head (FH) fastener, which secures the plug in place while the boat is underway and allows it to be backed out for draining. This is a single-piece plug and body assembly, sold as one item, and is intended for boaters who need a reliable, low-maintenance drain point for bilge water removal during storage or trailering.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sea-Dog\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 520040-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Machined Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter:\u003c\/strong\u003e 2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 1\/2 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFastener Type:\u003c\/strong\u003e #8 FH (fastener not included)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\/Finish:\u003c\/strong\u003e As Shown\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.29 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Items:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThis is a universal-fit garboard drain and plug intended for hulls with a 2 inch diameter, 1\/2 inch NPT garboard drain opening; it is not tied to a specific boat make or model.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat is the Sea-Dog 520040-1 Garboard Drain and Plug used for?\u003c\/strong\u003e It is a bronze drain fitting that threads into the garboard area of the hull, letting bilge water drain out when the boat is stored or trailered, and sealing the opening with the plug when underway.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the Sea-Dog garboard drain 520040-1?\u003c\/strong\u003e The body diameter is 2 inches, with a 1\/2 inch NPT thread size for installation into a matching drain opening.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 520040-1 garboard drain and plug made from?\u003c\/strong\u003e It is machined from bronze, chosen for its corrosion resistance in saltwater and freshwater marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Sea-Dog 520040-1 come with mounting fasteners?\u003c\/strong\u003e No, the fastener is not included; the plug uses a #8 FH (flat head) fastener that must be sourced separately.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Sea-Dog garboard drain and plug weigh?\u003c\/strong\u003e The Sea-Dog 520040-1 weighs 0.29 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 520040-1 sold as a single unit?\u003c\/strong\u003e Yes, it is sold as one complete drain and plug assembly, with a quantity of 1 item per unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this garboard drain plug specific to one boat brand or model?\u003c\/strong\u003e No, the Sea-Dog 520040-1 is a universal-fit fitting sized for a 2 inch, 1\/2 inch NPT garboard drain opening rather than a specific boat make or model.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread type does the 520040-1 garboard plug use?\u003c\/strong\u003e It uses a 1\/2 inch NPT (National Pipe Taper) thread for installation into the drain body.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the plug on the Sea-Dog 520040-1 be removed for draining and reinstalled?\u003c\/strong\u003e Yes, the bronze plug is designed to be threaded out to allow bilge water to drain and reinstalled to seal the opening when the boat is in the water.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat finish does the Sea-Dog garboard drain 520040-1 have?\u003c\/strong\u003e It has an as-shown bronze finish, consistent with the machined bronze construction of the part.\u003c\/p\u003e","brand":"Sea-Dog","offers":[{"title":"Default Title","offer_id":48988825419995,"sku":"S-D-520040-1","price":14.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/5244_eae7878c-1332-43d1-b0d4-3677a2b5e0fe.jpg?v=1784429705","url":"https:\/\/www.goodvibesmarina.com\/products\/sea-dog-520040-1-garboard-drain-plug-machined-bronze-1-2-npt-thread-2-flange","provider":"Good Vibes Marina","version":"1.0","type":"link"}
