Duplex stainless steel combines high strength with excellent resistance to pitting and crevice corrosion, making it a durable choice for below-waterline hardware where long-term reliability matters. The fitting is sized for 1-1\/2 inch hose and terminates in a barb end for a secure hose clamp connection, routing water intake, drainage, or discharge lines through the hull at a 90 degree angle to simplify hose runs in tight spaces.\u003c\/p\u003e\u003cp\u003eThe 6581X has a flange outer diameter of 2-3\/8 inches, a thread length of 1-5\/8 inches, a barb length of 1-1\/2 inches, and an overall length of 4 inches. It is rated for a maximum hull thickness of 1-1\/4 inches and requires a cut-out of 1-1\/2 inches for installation. At 1.8 pounds, it is a solid, purpose-built fitting for permanent hull penetrations on boats where a right-angle thru-hull is needed.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Whitecap Industries\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 6581X\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eType:\u003c\/strong\u003e Thru-Hull Fitting, 90 Degree\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Duplex Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Size:\u003c\/strong\u003e 1-1\/2 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange O.D.:\u003c\/strong\u003e 2-3\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length:\u003c\/strong\u003e 1-5\/8 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBarb Length:\u003c\/strong\u003e 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length:\u003c\/strong\u003e 4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCut Out:\u003c\/strong\u003e 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMax Hull Thickness:\u003c\/strong\u003e 1-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 1.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 725060658137\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat hose size does the Whitecap 6581X thru-hull fit?\u003c\/strong\u003e The Whitecap Industries 6581X is sized for 1-1\/2 inch hose, with a barb end designed to accept a 1-1\/2 inch hose and hose clamp.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat angle is this thru-hull fitting?\u003c\/strong\u003e It is a 90 degree thru-hull, meaning the hose barb exits at a right angle to the hull rather than straight through, which helps simplify hose routing in tight spaces.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the 6581X made from?\u003c\/strong\u003e Duplex stainless steel is used for the 6581X, chosen for its combination of strength and resistance to pitting and crevice corrosion in marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the maximum hull thickness this fitting supports?\u003c\/strong\u003e The 6581X is rated for hulls up to 1-1\/4 inches thick.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat size cut-out do I need to install the Whitecap 6581X?\u003c\/strong\u003e A 1-1\/2 inch cut-out is required to install the 6581X thru-hull fitting.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the overall length of the 6581X thru-hull?\u003c\/strong\u003e The overall length is 4 inches, with a barb length of 1-1\/2 inches and a thread length of 1-5\/8 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the Whitecap 6581X weigh?\u003c\/strong\u003e The 6581X weighs 1.8 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the flange outer diameter of the 6581X?\u003c\/strong\u003e The flange outer diameter is 2-3\/8 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the 6581X suitable for saltwater use?\u003c\/strong\u003e Yes, the duplex stainless steel construction of the 6581X resists pitting and crevice corrosion, making it suitable for both freshwater and saltwater use.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the hose attach to the 6581X thru-hull?\u003c\/strong\u003e The 6581X terminates in a barb fitting, and the hose is secured onto the barb with a hose clamp.\u003c\/p\u003e","brand":"Whitecap Industries","offers":[{"title":"Default Title","offer_id":49025295745243,"sku":"W-C-6581X","price":105.69,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/6581X_1ed04f83-8a92-4038-9339-f4bd25b3c1f3.jpg?v=1785001787","url":"https:\/\/www.goodvibesmarina.com\/products\/whitecap-industries-duplex-stainless-steel-90-degree-thru-hull-fitting-with-barb-1-1-2-inch","provider":"Good Vibes Marina","version":"1.0","type":"link"}
