Duravent 0512PI B-vent Round Rigid Pipe 5x12 in Double Wall

Product Description

The DURAVENT 0512PI is a double wall air-insulated B-vent round rigid pipe section designed to extend flue gas exhaust runs in Category I gas appliance venting systems. Built to a 5-inch diameter and 12-inch length, this pipe uses a double wall air-insulated construction that maintains safe surface temperatures while channeling combustion exhaust away from the appliance. The twist-lock connection system allows for secure, repeatable joints during assembly. Licensed HVAC technicians and gas appliance installers use this pipe section when building or extending B-vent runs in residential and light commercial settings.

This pipe section is suited for Category I natural draft gas appliances, including gas furnaces, water heaters, and boilers that require B-vent flue pipe. It is used in both new construction and retrofit venting projects where additional pipe length is needed to complete a vertical or horizontal vent run. The 5-inch diameter sizing matches standard B-vent system fittings and components within the same diameter family.

Key Features

• Double wall air-insulated construction for safe flue gas exhaust handling
• 5-inch diameter fits standard B-vent system components of matching size
• 12-inch rigid section for precise run extensions
• Twist-lock connection for secure, tool-assisted assembly
• Designed for Category I gas appliance venting applications

Compatibility

Designed as an OEM-style replacement and extension component for Category I gas appliance B-vent systems requiring 5-inch diameter double wall air-insulated pipe sections.

Installation Notes

Installation should be performed by a licensed HVAC technician or qualified gas appliance installer in accordance with NFPA 54 and the appliance manufacturer's venting instructions. Shut off gas supply and allow the appliance to cool completely before servicing or extending an existing vent run. Ensure all twist-lock joints are fully engaged and that the vent system maintains required clearances to combustibles as specified by local codes. Do not mix B-vent components of differing diameters without approved transition fittings.
