Crafted from certified Enhanced 316 stainless steel alloy, this fitting offers superior strength and lifetime corrosion resistance, making it a reliable choice for marine applications. The polished mirror finish on all visible areas not only provides a sleek look but also ensures added protection through passivation, guarding against the harsh marine environment. Designed with thick steel sidewalls, this thru-hull withstands continual stress and hose flexing, maintaining a secure connection over time. Installation is faster and simpler thanks to features like a silicone gasket for a tight seal, a channel under the flange for sealant application, and wrench flats or an end notch for easy gripping during tightening. The barbed tail ends accommodate multiple clamps, ensuring a secure fit for your hose connections. The standard thread model features a full-length thread suitable for thicker hulls, facilitating ease of installation. This thru-hull is intended for above-waterline use only, adhering to safety standards. Its specifications include a 1-1\/8\" inner diameter hose size, a 2-1\/4\" flange diameter, and a total length of approximately 3-7\/8\". The design also includes a 1-1\/4\" barb length for versatile hose attachment and a 1-1\/4\" install hole saw size. Engineered for durability and ease of installation, the Attwood Stainless Steel Thru-Hull Part 66549-3 is an excellent choice for marine professionals and boat enthusiasts seeking long-lasting, corrosion-resistant fittings that combine form and function seamlessly.\u003c\/p\u003e\u003cp\u003e\u003cb\u003eFeatures:\u003c\/b\u003e\u003c\/p\u003e\u003cul\u003e\u003cli\u003ePolished mirror finish on all visible areas with passivation for enhanced corrosion resistance\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eCast from certified Enhanced 316 stainless steel alloy for strength and longevity\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eThick steel sidewalls designed to withstand continuous stress and hose flexing\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eIncludes silicone gasket for a secure, trouble-free seal\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eChannel under flange for easy application of sealant\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eWrench flats or end notch for simple tightening from inside the hull\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eBarbed tail ends accommodate multiple clamps for secure hose connections\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eFull-length thread model suitable for thick hulls\u003c\/li\u003e\u003c\/ul\u003e\u003cul\u003e\u003cli\u003eDesigned for installation above the waterline for safety and durability\u003c\/li\u003e\u003c\/ul\u003e\u003cstyle\u003etable.productattributes, .productattributes td { border-bottom: 1px solid #ddd; border-collapse: collapse; padding: 2px; text-align: left; }\u003c\/style\u003e\n\u003ctable class=\"productattributes\"\u003e\n\u003cthead\u003e\u003ctr\u003e\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\u003ctd\u003eTruck Freight: No\u003c\/td\u003e\u003c\/tr\u003e\n\u003ctr\u003e\u003ctd\u003eOversized: No\u003c\/td\u003e\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003cbr\u003e","brand":"Attwood Marine","offers":[{"title":"Default Title","offer_id":44253878190169,"sku":"98091","price":43.97,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0623\/1818\/2489\/files\/98091XL.jpg?v=1785361051","url":"https:\/\/www.marinepartsonly.com\/products\/attwood-marine-stainless-steel-thru-hull-fitting-1-1-8-inner-diameter-standard-straight-barbed","provider":"Marine Parts Only","version":"1.0","type":"link"}
