It is built for below-waterline and above-waterline plumbing runs such as bailers, livewells, washdowns, and drain lines where a hose must pass cleanly through the hull. The fitting is molded from polypropylene for corrosion resistance in a marine environment and finished in white to blend with typical hull and deck gelcoat colors.\u003c\/p\u003e\u003cp\u003eThis connector accepts hose with an inside diameter of 1-1\/8 inch to 1-1\/4 inch and has a stem length of 3-1\/4 inch, making it suitable for hull sections up to 1-1\/4 inch in maximum thickness. Installation requires a 1-3\/8 inch hole drilled through the hull. The one-piece design allows the hose to be clamped directly to the stem on the interior side while the fitting body seats against the exterior hull surface, giving installers a straightforward through-hull hose connection without additional adapters.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Attwood\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 3874-3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Polypropylene\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Inside Diameter:\u003c\/strong\u003e 1-1\/8 inch to 1-1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStem Length:\u003c\/strong\u003e 3-1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Hull Thickness:\u003c\/strong\u003e 1-1\/4 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInstallation Hole Diameter:\u003c\/strong\u003e 1-3\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.2683 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size hose does the Attwood 3874-3 thru-hull fitting accept?\u003c\/strong\u003e The 3874-3 accepts hose with an inside diameter of 1-1\/8 inch to 1-1\/4 inch.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat diameter hole do I need to drill in the hull to install this fitting?\u003c\/strong\u003e Installing the Attwood 3874-3 requires a 1-3\/8 inch installation hole through the hull.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow thick a hull can the 3874-3 fitting be used on?\u003c\/strong\u003e This fitting is rated for hulls up to 1-1\/4 inch in maximum thickness.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the stem length of the Attwood 3874-3?\u003c\/strong\u003e The stem length is 3-1\/4 inch, measured from the fitting body to the end of the hose barb.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the Attwood 3874-3 thru-hull fitting made from?\u003c\/strong\u003e It is made from polypropylene, a corrosion-resistant plastic suited to marine hull fittings.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is the 3874-3 fitting?\u003c\/strong\u003e The 3874-3 has a white finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan the 3874-3 be used for a bailer or livewell drain line?\u003c\/strong\u003e Yes, it functions as a general-purpose thru-hull hose connector suitable for bailer, livewell, washdown, or drain hose runs that pass through the hull.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Attwood 3874-3 weigh?\u003c\/strong\u003e The Attwood 3874-3 weighs 0.2683 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the 3874-3 come with a hose clamp?\u003c\/strong\u003e The fitting itself is the thru-hull connector body; a separate hose clamp is used on the interior side to secure the hose to the stem.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the 3874-3 differ from the Attwood 3874-1?\u003c\/strong\u003e The 3874-3 and 3874-1 are both white polypropylene thru-hull connectors in the same 3874 series but are separate part numbers, so the correct one should be selected by part number to match the required hose and hull dimensions.\u003c\/p\u003e","brand":"Attwood","offers":[{"title":"Default Title","offer_id":48989669032155,"sku":"ATT-3874-3","price":8.14,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/61kluwQrksL.jpg?v=1784486754","url":"https:\/\/www.goodvibesmarina.com\/products\/attwood-3874-3-thru-hull-connector-fitting-white-polypropylene-fits-1-1-8-to-1-1-4-i-d-hose","provider":"Good Vibes Marina","version":"1.0","type":"link"}
