Measuring 7 inches in diameter and 60 inches in length, this pipe maintains flue gas temperature throughout extended vent runs by trapping an insulating air layer between its inner and outer walls. The twist-lock connection system allows for secure, repeatable assembly without additional fasteners. Licensed HVAC technicians and plumbers install this component as part of vertical or horizontal B-vent runs serving natural gas and propane appliances.\u003c\/p\u003e\u003cp\u003eThis pipe section is suited for residential and light commercial applications where Category I gas appliances require a compliant Type B vent pathway. The 60-inch length makes it well-suited for long straight runs between fittings, reducing the number of joints in a system. Typical installations include gas furnaces, boilers, water heaters, and other non-positive-pressure vented appliances. The double wall air-insulated design helps preserve the buoyancy of flue gases, supporting reliable draft performance across the full vent system.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e7-inch diameter by 60-inch length for extended straight vent runs\u003c\/li\u003e\n\u003cli\u003eDouble wall air-insulated construction maintains flue gas temperature and draft\u003c\/li\u003e\n\u003cli\u003eTwist-lock connection system provides secure, tool-assisted assembly\u003c\/li\u003e\n\u003cli\u003eDesigned for Category I gas appliance venting applications\u003c\/li\u003e\n\u003cli\u003eRound rigid pipe profile for consistent airflow and structural integrity\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement and system component for Type B gas vent installations serving Category I natural gas and propane appliances.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a licensed HVAC technician or plumber in accordance with the International Fuel Gas Code and the appliance manufacturer's venting instructions. Shut off gas supply and allow the system to cool completely before servicing or extending an existing vent run. Ensure all twist-lock joints are fully engaged and that required clearances to combustibles are maintained throughout the run. Do not use B-vent components with positive-pressure or Category III or IV appliances.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 7 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 60 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction\u003c\/strong\u003e: Double Wall Air-Insulated\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Shape\u003c\/strong\u003e: Round\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePipe Type\u003c\/strong\u003e: Rigid\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVent Category\u003c\/strong\u003e: Category I (Type B)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConnection Type\u003c\/strong\u003e: Twist-Lock\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\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: 0705PI\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"DURAVENT","offers":[{"title":"Default Title","offer_id":51346651054386,"sku":"0705PI","price":161.55,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/310553346.jpg?v=1782086689","url":"https:\/\/voomisupply.com\/products\/duravent-0705pi-b-vent-round-rigid-pipe-7x60-in-double-wall","provider":"Voomi Supply","version":"1.0","type":"link"}
