Thru hull fittings like the TH-1000-W create the watertight passage where seacocks, strainers, or hose barbs connect to plumbing, cooling, or drain systems that pass through a boat's hull. The built-in grounding nut allows a bonding wire to be attached directly to the fitting, helping protect underwater hardware from galvanic corrosion by tying it into the boat's bonding system.\u003c\/p\u003e\u003cp\u003eBronze construction gives this fitting strong resistance to saltwater corrosion, making it suitable for long-term below-waterline installation. The 1 inch size refers to the fitting's thru hull opening, so it should be matched to hose, seacock, or strainer components rated for the same 1 inch size. As a component sold with its grounding nut included, it is ready to be wired into a bonding system during installation.\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 TH-1000-W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize:\u003c\/strong\u003e 1 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncludes Grounding Nut:\u003c\/strong\u003e Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.83125 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Dimensions:\u003c\/strong\u003e 9.5 x 4.63 x 4.8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 742985064119\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Thru Hull Fittings and Strainers\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size is the Groco TH-1000-W thru hull fitting?\u003c\/strong\u003e The TH-1000-W is a 1 inch thru hull fitting, so it should be paired with hose, seacock, or strainer hardware rated for the same 1 inch size.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the TH-1000-W come with a grounding nut?\u003c\/strong\u003e Yes, the Groco TH-1000-W includes a grounding nut built into the fitting, allowing a bonding wire to be attached for corrosion protection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Groco TH-1000-W made from?\u003c\/strong\u003e This thru hull fitting is made of bronze, chosen for its resistance to corrosion in saltwater and below-waterline marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Groco TH-1000-W weigh?\u003c\/strong\u003e The TH-1000-W weighs 0.83125 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the package dimensions of the TH-1000-W?\u003c\/strong\u003e The Groco TH-1000-W ships in packaging measuring 9.5 x 4.63 x 4.8 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is a grounding nut used for on a thru hull fitting?\u003c\/strong\u003e A grounding nut on the TH-1000-W provides an attachment point for a bonding wire, tying the underwater fitting into the boat's bonding system to help reduce galvanic corrosion.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the Groco TH-1000-W suitable for below-waterline installation?\u003c\/strong\u003e Yes, thru hull fittings such as the TH-1000-W are designed to be installed below the waterline as the through-hull connection point for plumbing or drain systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat category of part is the TH-1000-W?\u003c\/strong\u003e The Groco TH-1000-W is listed under thru hull fittings and strainers, the category of hardware that creates watertight hull penetrations for onboard systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included with the Groco TH-1000-W?\u003c\/strong\u003e The TH-1000-W thru hull fitting is supplied with its grounding nut as a single unit.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the TH-1000-W be used with a seacock?\u003c\/strong\u003e The TH-1000-W is a 1 inch thru hull fitting intended to connect to matching 1 inch seacock or strainer hardware at the hull penetration point.\u003c\/p\u003e","brand":"Groco","offers":[{"title":"Default Title","offer_id":49031098171611,"sku":"GRO-TH-1000W","price":22.64,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/51L00pdqf6L.jpg?v=1785208696","url":"https:\/\/www.goodvibesmarina.com\/products\/groco-bronze-thru-hull-fitting-with-grounding-nut-1-inch-th-1000-w","provider":"Good Vibes Marina","version":"1.0","type":"link"}
