The pipe has a nominal diameter of 5 inches and an overall length of 12 inches, with an adjustable range from 3.5 inches to 10.5 inches. This adjustability allows the installer to fine-tune the section length to fit the exact spacing needed within a vent system without cutting. Licensed HVAC technicians and plumbers install this type of component when connecting gas-fired furnaces, water heaters, boilers, or other Category I appliances to a Type B double-wall vent system.\u003c\/p\u003e\n\u003cp\u003eThis adjustable pipe section is suited for residential and light commercial venting installations where a fixed-length section would not bridge the gap between two vent components cleanly. It is used in vertical and near-vertical B-vent runs where the appliance draft hood collar connects to the main vent stack. The 5-inch diameter fits vent systems sized for mid-range BTU input appliances. Contractors use adjustable sections like this during new installations and service replacements when existing vent routing requires precise field fitting.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eAdjustable length from 3.5 inches to 10.5 inches within a 12-inch nominal section\u003c\/li\u003e\n  \u003cli\u003e5-inch round diameter for mid-range residential and light commercial vent systems\u003c\/li\u003e\n  \u003cli\u003eType B double-wall construction suitable for Category I gas appliance venting\u003c\/li\u003e\n  \u003cli\u003eField-adjustable design eliminates cutting during installation\u003c\/li\u003e\n  \u003cli\u003eCompatible with standard B-vent system components of matching diameter\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement or new-installation component for Type B double-wall gas vent systems with a 5-inch nominal pipe diameter.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and applicable local codes, including the International Fuel Gas Code (IFGC). Shut off the gas supply and allow the appliance to cool completely before disconnecting any vent sections. Ensure all joints are fully seated and secured per the vent system manufacturer guidelines. Do not use Type B vent pipe for high-temperature Category III or Category IV appliance exhaust applications.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Diameter\u003c\/strong\u003e: 5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal Section Length\u003c\/strong\u003e: 12 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eAdjustable Length Range\u003c\/strong\u003e: 3.5 inches to 10.5 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVent Type\u003c\/strong\u003e: Type B Double-Wall B-Vent\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eShape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: DURAVENT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 0512ADJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURAVENT","offers":[{"title":"Default Title","offer_id":51346013389106,"sku":"0512ADJ","price":43.12,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555445.jpg?v=1782068971","url":"https:\/\/voomisupply.com\/products\/duravent-0512adj-b-vent-round-adjustable-pipe-5x12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
