One end of the fitting is threaded with a 3\/4 inch-14 thread to install directly into a pump outlet, thru-hull, or fitting port, while the opposite end is designed to accept a Flow-Rite Qwik-Lok coupler, allowing hose sections to be connected and disconnected quickly without tools. This makes the 3899-3 a practical choice for boat owners who want a fast-release connection point in their plumbing run instead of a fixed barbed hose joint.\u003c\/p\u003e\u003cp\u003eThe fitting is finished in white and constructed with a machined stainless steel body, giving it corrosion resistance for continuous exposure to saltwater and bilge environments. Its compact size allows it to fit into tight plumbing runs typical of livewell and baitwell systems. Because it uses the Flow-Rite Qwik-Lok coupling standard, it pairs with other Qwik-Lok equipped hose ends and fittings in the same plumbing system, simplifying maintenance and hose changes.\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 3899-3\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFitting Type:\u003c\/strong\u003e Thread-to-Flow-Rite Qwik-Lok Connector\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Pump Flow Rate:\u003c\/strong\u003e 500-800 GPH pumps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 3\/4 inch-14\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior Finish:\u003c\/strong\u003e Machined\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Dimensions:\u003c\/strong\u003e 4.5 x 9.25 x 3.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.085 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat does the Attwood 3899-3 connect?\u003c\/strong\u003e It joins a threaded pump or fitting port on one end to a Flow-Rite Qwik-Lok coupler on the other, letting a hose line be connected or released without tools.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat pumps is the 3899-3 fitting designed for?\u003c\/strong\u003e This connector is intended for use with 500-800 GPH pumps, such as those used in livewell, baitwell, and washdown plumbing systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the thread size on the Attwood 3899-3?\u003c\/strong\u003e The threaded end of the 3899-3 uses a 3\/4 inch-14 thread that installs into a matching pump or fitting port.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 3899-3 made of plastic or metal?\u003c\/strong\u003e The Attwood 3899-3 has a machined stainless steel body, giving it corrosion resistance for marine plumbing use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat color is this fitting?\u003c\/strong\u003e The Attwood 3899-3 is finished in white.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Attwood 3899-3 weigh?\u003c\/strong\u003e The 3899-3 connector fitting weighs 0.085 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the 3899-3 fitting?\u003c\/strong\u003e As packaged, the Attwood 3899-3 measures 4.5 x 9.25 x 3.5 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDo I need a separate Qwik-Lok coupler to use this fitting?\u003c\/strong\u003e Yes, the 3899-3 provides the threaded connection point and Qwik-Lok end; a mating Flow-Rite Qwik-Lok coupler on the hose side is needed to complete the quick-release connection.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs there a barb-style version instead of the Qwik-Lok connector?\u003c\/strong\u003e Yes, the Attwood 3899-1 is the barb-connection version in the same fitting family, for those who prefer a hose barb over the Qwik-Lok quick-connect.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan this fitting be used with any pump, or only specific flow rates?\u003c\/strong\u003e The 3899-3 is designed for use with 500-800 GPH pumps rather than higher-flow models.\u003c\/p\u003e","brand":"Attwood","offers":[{"title":"Default Title","offer_id":48989670899931,"sku":"ATT-3899-3","price":9.16,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/att-3899-3_lg_1__55310.1558113248.500.750.jpg?v=1785188837","url":"https:\/\/www.goodvibesmarina.com\/products\/attwood-3899-3-thread-to-qwik-lok-aerator-pump-connector-fitting-fits-a-series-and-tsunami-500-800-gph-pumps-flow-rite-qwik-lok","provider":"Good Vibes Marina","version":"1.0","type":"link"}
