This pipe adjusts from 3.5 inches to 10.5 inches in length within a nominal 12-inch section, making it a practical solution for fine-tuning vent run lengths during installation. With a 3-inch diameter, it fits standard Type B double-wall vent systems used on furnaces, water heaters, and other Category I gas appliances. Licensed plumbers, HVAC technicians, and gas-fitter contractors install this component as part of a compliant vent assembly.\u003c\/p\u003e\n\u003cp\u003eThis adjustable pipe section is suited for residential and light commercial applications where a fixed-length pipe would leave a gap or require cutting. It is used in Type B vent systems serving gas-fired furnaces, boilers, and water heaters that require a listed double-wall vent connector. The adjustable design eliminates the need to cut rigid pipe to fit, saving time on the job and reducing material waste during rough-in or retrofit venting work.\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\u003e3-inch diameter fits standard Type B double-wall vent systems\u003c\/li\u003e\n  \u003cli\u003eEliminates cutting of rigid pipe for short or irregular run lengths\u003c\/li\u003e\n  \u003cli\u003eDesigned for Category I natural gas and propane appliance venting\u003c\/li\u003e\n  \u003cli\u003eRound pipe profile for consistent fit with compatible Type B vent fittings\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style replacement and new-installation component for 3-inch Type B double-wall gas vent systems in residential and light commercial applications.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation must be performed by a licensed HVAC technician, plumber, or qualified gas-fitter in accordance with NFPA 54 and the International Fuel Gas Code (IFGC). Shut off the gas supply and allow the appliance to cool completely before servicing or extending any vent assembly. All joints in the vent run should be secured per the manufacturer instructions and local authority having jurisdiction requirements. Do not mix Type B vent components from different manufacturers within the same listed vent system unless the manufacturers explicitly certify cross-brand compatibility.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Diameter\u003c\/strong\u003e: 3 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eNominal 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\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eProfile\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: 0312ADJ\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURAVENT","offers":[{"title":"Default Title","offer_id":51342725939506,"sku":"0312ADJ","price":35.03,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310555437.jpg?v=1782004773","url":"https:\/\/voomisupply.com\/products\/duravent-0312adj-b-vent-round-adjustable-pipe-3x12-in","provider":"Voomi Supply","version":"1.0","type":"link"}
