It measures 8 inches in diameter and 5 feet in length, featuring an aluminum inner wall and a galvanized steel outer wall. This construction provides the thermal performance and corrosion resistance required for venting natural gas and propane appliances that produce non-positive vent pressure and flue gas temperatures that will not exceed the limits of Type B vent systems. Licensed HVAC technicians and plumbers install this pipe as part of compliant Category 1 venting assemblies in residential and light commercial settings.\u003c\/p\u003e\n\u003cp\u003eThis pipe section is suited for venting Category 1 gas appliances such as furnaces, boilers, and water heaters that operate with non-positive vent static pressure and low-heat flue gases. The 8-inch diameter accommodates larger residential or light commercial appliance venting requirements. It is typically installed as a straight run section within a complete Type B vent system and connects with compatible Hart Cooley elbows, tees, and termination fittings to form a code-compliant vent assembly.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eDouble-wall construction with aluminum inner wall and galvanized outer wall for durability and thermal performance\u003c\/li\u003e\n  \u003cli\u003e8-inch diameter accommodates higher-capacity Category 1 appliance venting\u003c\/li\u003e\n  \u003cli\u003e5-foot length reduces the number of joints needed in straight runs\u003c\/li\u003e\n  \u003cli\u003eRound pipe shape for standard Type B vent system compatibility\u003c\/li\u003e\n  \u003cli\u003eRated for Category 1 venting — non-positive static pressure, low-heat flue gas applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned as an OEM-style component for use in Type B double-wall gas vent systems serving Category 1 rated gas appliances.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation of Type B gas vent pipe should be performed by a licensed HVAC technician or plumber in accordance with the International Fuel Gas Code (IFGC) and local authority having jurisdiction requirements. Shut off and lock out the gas supply and disconnect power to the appliance before servicing or modifying any vent sections. Do not use Type B vent pipe with appliances that produce positive vent pressure, Category II, III, or IV exhaust gases, or with solid or liquid fuel burning equipment. Verify that all joints are fully seated and secured per the manufacturer assembly instructions before returning the appliance to service.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eDiameter\u003c\/strong\u003e: 8 inches\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 5 feet (60 inches)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003ePipe Shape\u003c\/strong\u003e: Round\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\u003eAppliance Category\u003c\/strong\u003e: Category 1\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eInner Wall Material\u003c\/strong\u003e: Aluminum\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eOuter Wall Material\u003c\/strong\u003e: Galvanized Steel\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 12.66 pounds\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: HART COOLEY\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 8r5\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"HART \u0026 COOLEY","offers":[{"title":"Default Title","offer_id":51234006204722,"sku":"8R5","price":161.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/307633002.jpg?v=1780114752","url":"https:\/\/voomisupply.com\/products\/hart-cooley-8r5-type-b-vent-round-pipe-8-in-x-5-ft","provider":"Voomi Supply","version":"1.0","type":"link"}
