By introducing an air break at the highest point of the hose run, a vented loop like the HVL-1500 stops water from being siphoned back into the boat when the vessel heels or when water levels shift, which is a common cause of unwanted flooding through thru-hull plumbing.\u003c\/p\u003e\u003cp\u003eConstructed from plastic with a bronze finish, the HVL-1500 is sized for 1-1\/2 inch hose and is supplied as a single unit. It carries a nominal wall thickness of 0.125 inches and measures 8 inches by 7 inches. This fitting is intended to be installed in-line on hose runs where anti-siphon protection is required, and is compatible with standard 1-1\/2 inch marine hose.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e GROCO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e HVL-1500\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHose Size:\u003c\/strong\u003e 1-1\/2 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Plastic\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e Bronze\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Dimensions:\u003c\/strong\u003e 8 inches L x 7 inches W\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNominal Wall Thickness:\u003c\/strong\u003e 0.125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eItem Length:\u003c\/strong\u003e 10 feet\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 2.8 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUnit Count:\u003c\/strong\u003e 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 742985002715\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits 1-1\/2 inch hose runs.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003eNo OEM cross-reference numbers are listed for the GROCO HVL-1500.\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat size hose does the GROCO HVL-1500 vented loop fit?\u003c\/strong\u003e The GROCO HVL-1500 is sized for 1-1\/2 inch hose.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is a vented loop used for?\u003c\/strong\u003e A vented loop like the HVL-1500 creates an air break at the top of a hose run to stop water from being siphoned back through the plumbing, which helps prevent unwanted flooding on below-waterline hose runs.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat material is the HVL-1500 made from?\u003c\/strong\u003e The HVL-1500 is made from plastic with a bronze finish.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the GROCO HVL-1500 weigh?\u003c\/strong\u003e The HVL-1500 weighs 2.8 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat are the dimensions of the HVL-1500?\u003c\/strong\u003e The HVL-1500 measures 8 inches long by 7 inches wide.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the wall thickness of the HVL-1500?\u003c\/strong\u003e It has a nominal wall thickness of 0.125 inches.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow many units come in a package of the HVL-1500?\u003c\/strong\u003e The HVL-1500 is sold as a single unit (unit count of 1).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eDoes the HVL-1500 replace a specific OEM part number?\u003c\/strong\u003e No OEM cross-reference or replacement part numbers are listed for the GROCO HVL-1500.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs the GROCO HVL-1500 a genuine GROCO part?\u003c\/strong\u003e Yes, the HVL-1500 is a genuine GROCO product, identified by GROCO part number HVL-1500.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhere is a vented loop typically installed on a boat?\u003c\/strong\u003e Vented loops such as the HVL-1500 are typically installed in-line on below-waterline hose runs, including head discharge and other drain lines, at the highest point of the run.\u003c\/p\u003e","brand":"Groco","offers":[{"title":"Default Title","offer_id":49031097090267,"sku":"GRO-HVL-1500","price":207.2,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/61GL9xCG7wL.jpg?v=1785208673","url":"https:\/\/www.goodvibesmarina.com\/products\/groco-bronze-vented-loop-1-1-2-inch-hose-anti-siphon-valve","provider":"Good Vibes Marina","version":"1.0","type":"link"}
