Precision-cast in one piece and CNC-finished for exact dimensions, each fitting maintains a true 90° angle, so connected tubing runs straight into the next section without kinking or strain. The marine-grade 316 alloy—with its molybdenum content— stands up to salt spray, bilge moisture, and constant humidity far longer than 304 fittings or chrome-plated brass, making these elbows suitable for everything from livewell plumbing to raw water intake lines. A full mirror polish inside and out isn't just about looks: the smooth surface resists salt deposits, makes cleaning simple, and reduces flow restriction. Four popular tubing sizes are available—22 mm, 25 mm, 30 mm, and 32 mm outer diameters—each secured with a hex set screw for a reliable grip on inserted tubing. Whether replacing a corroded original elbow on an aging sportfisher, plumbing a new washdown pump on a center console, or building custom handrails and arch frames, these fittings bring together the corrosion-proof longevity and clean finish that serious boat maintenance demands.\u003c\/p\u003e\n\u003ch2\u003e✨ Key Features of 316 Stainless Steel 90° Elbow Fittings\u003c\/h2\u003e\n\u003cul class=\"gbs-features-list\"\u003e\n\u003cli class=\"gbs-feature-item\"\u003e\u003cspan\u003e\u003cstrong\u003eTrue Marine 316 Stainless Steel:\u003c\/strong\u003e Molybdenum-enriched alloy offers superior pitting resistance in saltwater and coastal environments compared to standard 304.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"gbs-feature-item\"\u003e\u003cspan\u003e\u003cstrong\u003eOne-Piece CNC Precision Casting:\u003c\/strong\u003e No welded seams or glued joints—each elbow is machined from a single casting for consistent wall thickness and distortion-free angles.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"gbs-feature-item\"\u003e\u003cspan\u003e\u003cstrong\u003eFull Mirror Polish Finish:\u003c\/strong\u003e Polished inside and out to reduce flow friction, resist salt buildup, and maintain a clean appearance with minimal maintenance.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"gbs-feature-item\"\u003e\u003cspan\u003e\u003cstrong\u003eHex Set Screw Retention:\u003c\/strong\u003e Each elbow includes a stainless hex grub screw that locks inserted tubing firmly in place without the need for bulky hose clamps.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"gbs-feature-item\"\u003e\u003cspan\u003e\u003cstrong\u003eFour Common Marine Sizes:\u003c\/strong\u003e 22 mm, 25 mm, 30 mm, and 32 mm outer diameters cover most tubing found on yachts and powerboats.\u003c\/span\u003e\u003c\/li\u003e\n\u003cli class=\"gbs-feature-item\"\u003e\u003cspan\u003e\u003cstrong\u003eVersatile Plumbing Applications:\u003c\/strong\u003e Suitable for raw water intake, livewell circulation, deck drain routing, fuel line bends, and structural rail fittings.\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003e📏 Model Dimensions – 90° Elbow Sizes\u003c\/h2\u003e\n\u003cdiv class=\"gbs-specs-table-wrapper\"\u003e\n\u003ctable class=\"gbs-specs-table\"\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eModel\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eOD (Tubing)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eA (Port ID)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eB (Arm Length)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e\u003cstrong\u003eC (Arm Length)\u003c\/strong\u003e\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel 1\u003c\/td\u003e\n\u003ctd\u003e22 mm\u003c\/td\u003e\n\u003ctd\u003e22.6 mm\u003c\/td\u003e\n\u003ctd\u003e50 mm\u003c\/td\u003e\n\u003ctd\u003e50 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel 2\u003c\/td\u003e\n\u003ctd\u003e25 mm\u003c\/td\u003e\n\u003ctd\u003e25.7 mm\u003c\/td\u003e\n\u003ctd\u003e51 mm\u003c\/td\u003e\n\u003ctd\u003e51 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel 3\u003c\/td\u003e\n\u003ctd\u003e30 mm\u003c\/td\u003e\n\u003ctd\u003e30.5 mm\u003c\/td\u003e\n\u003ctd\u003e54 mm\u003c\/td\u003e\n\u003ctd\u003e54 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel 4\u003c\/td\u003e\n\u003ctd\u003e32 mm\u003c\/td\u003e\n\u003ctd\u003e32.6 mm\u003c\/td\u003e\n\u003ctd\u003e55 mm\u003c\/td\u003e\n\u003ctd\u003e55 mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp style=\"font-size: 0.85rem; color: #777; margin-top: 6px;\"\u003e* All dimensions in millimeters.

The elbow is designed to slip over tubing with the matching OD—22 mm, 25 mm, 30 mm, or 32 mm. The internal port opening (dimension A) is slightly larger than the listed OD to allow a snug push-fit before tightening the set screw.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gbs-faq-item\"\u003e\n\u003ch3 class=\"gbs-faq-question\"\u003eQ: Will the mirror polish finish last in saltwater conditions?\u003c\/h3\u003e\n\u003cp class=\"gbs-faq-answer\"\u003eA: 316 stainless steel naturally resists pitting and corrosion in marine environments. The mirror polish adds an extra barrier by closing the microscopic pores on the metal surface where salt could lodge. Rinse with fresh water occasionally, and the finish will maintain its shine for years.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gbs-faq-item\"\u003e\n\u003ch3 class=\"gbs-faq-question\"\u003eQ: Can I use this elbow for fuel lines on my outboard?\u003c\/h3\u003e\n\u003cp class=\"gbs-faq-answer\"\u003eA: Yes. 316 stainless is compatible with gasoline, diesel, and ethanol-blended fuels. The smooth internal bore minimizes flow restriction, and the set screw holds the fuel hose securely. Always double-check that your hose's inner diameter matches the elbow's outer diameter for a proper seal.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gbs-faq-item\"\u003e\n\u003ch3 class=\"gbs-faq-question\"\u003eQ: Does the set screw damage the tubing over time?\u003c\/h3\u003e\n\u003cp class=\"gbs-faq-answer\"\u003eA: The hex screw applies a localized pinch to hold the tubing in place. For rigid tubing like stainless or aluminum pipe, this creates a secure mechanical lock. For softer materials like rubber or silicone hose, we recommend placing a small protective shim between the screw tip and the hose surface, or using the elbow with rigid tubing where possible.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"gbs-faq-item\"\u003e\n\u003ch3 class=\"gbs-faq-question\"\u003eQ: Can these elbows be used to build a custom boat railing or arch?\u003c\/h3\u003e\n\u003cp class=\"gbs-faq-answer\"\u003eA: Absolutely. Beyond plumbing, the 22 mm and 25 mm sizes in particular are common for tubular railings, radar arches, and grab handles. The mirror polish finish matches typical marine brightwork, and the 316 alloy won't develop surface rust like lower-grade stainless.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e","brand":"HomeDIYer","offers":[{"title":"22mm（316 Stainless Steel）","offer_id":52266356834578,"sku":"HKTBCLA330001","price":27.8,"currency_code":"USD","in_stock":true},{"title":"25mm（316 Stainless Steel）","offer_id":52266356867346,"sku":"HKTBCLA330002","price":28.8,"currency_code":"USD","in_stock":true},{"title":"30mm（316 Stainless Steel）","offer_id":52266356900114,"sku":"HKTBCLA330003","price":31.8,"currency_code":"USD","in_stock":true},{"title":"32mm（316 Stainless Steel）","offer_id":52266356932882,"sku":"HKTBCLA330004","price":34.8,"currency_code":"USD","in_stock":true},{"title":"38mm（316 Stainless Steel）","offer_id":52266356965650,"sku":"HKTBCLA330005","price":41.8,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0884\/8936\/1682\/files\/O1CN01JaP8yK25h9mB5S9qy__826417557.jpg?v=1778588327","url":"https:\/\/homediyer.com\/de\/products\/316-stainless-steel-90-degree-elbow-marine","provider":"HomeDIYer","version":"1.0","type":"link"}
