It features a 0.5 inch NPT threaded connection paired with a barb connector, allowing a hose to be clamped directly onto the fitting for a tight, leak-resistant seal. The bronze construction is well suited to continuous saltwater and freshwater exposure, making this fitting a common choice for bilge pump discharge, raw water intake, washdown, and other plumbing runs that pass through the hull.\u003c\/p\u003e\u003cp\u003eMeasuring 4 x 3 x 3 inches overall, the HTH-500 is compact enough for typical hull thicknesses while providing a solid mounting base. It is supplied as a single-piece fitting (1 unit) and is backed by a manufacturer warranty. This thru-hull fitting is intended as a below-waterline plumbing component and should be paired with an appropriate seacock or backing arrangement per standard marine plumbing practice.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Groco\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e HTH-500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Name:\u003c\/strong\u003e Bronze Thru-Hull Fitting w\/Nut, 1\/2 Inch Hose\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Thru-Hull Fittings \u0026amp; Strainers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor\/Finish:\u003c\/strong\u003e Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnector Type:\u003c\/strong\u003e Barb\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 0.5 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type:\u003c\/strong\u003e NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 4 x 3 x 3 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Pieces:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.4375 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat hose size does the Groco HTH-500 thru-hull fitting accept?\u003c\/strong\u003e The HTH-500 is sized for 1\/2 inch hose, with a barb connector designed to accept and hold a 1\/2 inch inner-diameter hose with a clamp.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Groco HTH-500 made from?\u003c\/strong\u003e This thru-hull fitting is made from bronze, a material chosen for its resistance to corrosion in both saltwater and freshwater marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat thread type and size does this fitting use?\u003c\/strong\u003e The HTH-500 uses a 0.5 inch NPT (National Pipe Thread) connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the overall dimensions of the HTH-500 thru-hull fitting?\u003c\/strong\u003e The Groco HTH-500 measures 4 x 3 x 3 inches overall.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Groco HTH-500 weigh?\u003c\/strong\u003e The HTH-500 weighs 0.4375 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the Groco HTH-500 come with a nut?\u003c\/strong\u003e Yes, the HTH-500 is a thru-hull fitting supplied with a nut for securing it through the hull.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the HTH-500 typically used for on a boat?\u003c\/strong\u003e The Groco HTH-500 bronze thru-hull fitting is commonly used for below-waterline plumbing connections such as bilge pump discharge, raw water intake, or washdown lines where a hose needs to pass through the hull.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Groco HTH-500 sold as a single unit?\u003c\/strong\u003e Yes, the HTH-500 is sold as one piece (a single fitting), not as a multi-pack.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Groco HTH-500 backed by a warranty?\u003c\/strong\u003e Yes, the HTH-500 is backed by a manufacturer warranty.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs bronze a good choice for a below-waterline fitting like the HTH-500?\u003c\/strong\u003e Bronze is a standard material for below-waterline marine hardware because it resists corrosion from prolonged saltwater and freshwater exposure, which is why Groco uses it for the HTH-500 thru-hull fitting.\u003c\/p\u003e","brand":"Groco","offers":[{"title":"Default Title","offer_id":49031096959195,"sku":"GRO-HTH-500","price":15.09,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/51EkBEiRSwL_66dd69b7-6b13-4d4c-8266-215a283f5291.jpg?v=1785208669","url":"https:\/\/www.goodvibesmarina.com\/products\/groco-bronze-hose-barb-thru-hull-fitting-hth-500-1-2-inch-npt","provider":"Good Vibes Marina","version":"1.0","type":"link"}
