The plug uses a 3\/4 inch NPT tapered thread, which draws down tighter as it is turned in to create a watertight seal against the hull fitting without requiring a separate gasket or sealant. A T-handle head lets the plug be hand-tightened and removed without wrenches or tools, which is useful when a boat needs to be drained quickly on a trailer or in dry storage. Bronze construction resists the corrosion that saltwater and constant wet\/dry cycling cause in plain steel hardware, making it suited to long-term use in a through-hull drain location. The plug measures 3-1\/2 inches overall with a 3\/4 inch NPT thread size, and is designed as a direct fit for garboard drain fittings machined to that same 3\/4 inch NPT thread. It is intended as a replacement plug and is cross-referenced to Sea-Dog part number 520046-1.\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 520047-1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Garboard Drain T-Handle Plug\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Die Cast Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 3\/4 inch NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length:\u003c\/strong\u003e 3-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.466 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeal Type:\u003c\/strong\u003e Tapered NPT thread, watertight\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits garboard drain openings machined with a 3\/4 inch NPT thread.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cul\u003e\u003cli\u003e520046-1\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat thread size does the Sea-Dog 520047-1 garboard drain plug use?\u003c\/strong\u003e The Sea-Dog 520047-1 uses a 3\/4 inch NPT tapered thread, which draws tight as it is screwed in to create a watertight seal in the garboard drain fitting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 520047-1 plug made of metal or plastic?\u003c\/strong\u003e It is die cast bronze, chosen for its resistance to corrosion in the wet, saltwater-exposed environment of a garboard drain opening.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes this plug require tools to install or remove?\u003c\/strong\u003e No tools are needed.
