Cast from solid bronze for long-term resistance to saltwater and freshwater corrosion, each fitting combines a flanged mushroom head on the outside of the hull with a threaded hose barb shank on the inside, secured by a bronze locknut for a watertight, high-pressure seal. These fittings are used throughout the boat for bilge pump discharge, washdown intake, raw water intake and discharge, livewell plumbing, and other through-hull hose runs where reliability cannot be compromised.\u003c\/p\u003e\u003cp\u003eEvery Groco thru-hull fitting is precision cast and machined to hold up under continuous submersion and vibration, with a heavy nominal wall thickness that resists cracking, pitting, and dezincification far longer than plastic or low-grade alloy alternatives. Whether you are replacing a corroded fitting or plumbing a new through-hull run, this line covers the common hose sizes found on recreational and light commercial vessels.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eBrand: Groco\u003c\/li\u003e\n\u003cli\u003eMaterial: Solid bronze construction\u003c\/li\u003e\n\u003cli\u003eStyle: Mushroom-head thru-hull with hose barb and mounting nut\u003c\/li\u003e\n\u003cli\u003eMaximum pressure rating: 2000 PSI\u003c\/li\u003e\n\u003cli\u003eAvailable hose sizes: 5\/8 Inch and 1-1\/2 Inch\u003c\/li\u003e\n\u003cli\u003eCorrosion resistant for saltwater and freshwater service\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSizes \u0026amp; Options\u003c\/h3\u003e\u003cp\u003eThis thru-hull fitting is sold by hose barb size, and matching the size to your existing hose run is critical for a leak-free installation. Measure the inside diameter (ID) of the hose you are connecting to and choose the fitting whose barb matches that ID exactly - a barb that is too small or too large will not seal properly even with hose clamps. The 5\/8 Inch (HTH-625) fitting suits smaller washdown, livewell, and drain lines, while the 1-1\/2 Inch (HTH-1500) fitting is sized for larger bilge pump discharge and raw water lines. If you are replacing an existing thru-hull, match the hose size of the fitting being removed rather than the hole diameter alone.\u003c\/p\u003e","brand":"Groco","offers":[{"title":"1-1\/2\"","offer_id":49048081203419,"sku":"GRO-HTH-1500","price":50.34,"currency_code":"USD","in_stock":false},{"title":"5\/8\"","offer_id":49048081236187,"sku":"GRO-HTH-625","price":19.21,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/51EkBEiRSwL_1ac3da23-38ed-4c3b-a497-f1e2fcf8fb3f.jpg?v=1785433763","url":"https:\/\/www.goodvibesmarina.com\/products\/groco-bronze-thru-hull-fitting-with-hose-barb-available-in-5-8-to-1-1-2","provider":"Good Vibes Marina","version":"1.0","type":"link"}
