Duravent 0505PI B-vent Round Rigid Pipe 5x60 Inches

Product Description

The DURAVENT 0505PI is a double-wall, air-insulated B-vent round rigid pipe section designed for use in Category I gas appliance venting systems. The pipe measures 5 inches in diameter and 60 inches in length, providing extended vent run capability without the need for multiple short sections. Double-wall air-insulated construction maintains flue gas temperature throughout the vent run, supporting proper draft and reducing the risk of condensation inside the flue. Licensed HVAC technicians and gas appliance installers use this pipe section in both new construction and retrofit venting assemblies.

This pipe section is suited for residential and light commercial installations where a Category I gas appliance requires a B-vent system. Common applications include venting natural gas and propane furnaces, boilers, water heaters, and other Category I appliances that produce positive-pressure or natural-draft flue gases. The 60-inch length makes it appropriate for long vertical or horizontal vent runs where fewer joints are preferred. Twist-lock connections allow the pipe to join with compatible B-vent fittings, elbows, and terminations in the same diameter series.

Key Features

• Double-wall air-insulated construction maintains flue gas temperature and supports proper draft
• 5-inch diameter x 60-inch length suits extended vent runs with fewer joints
• Twist-lock connection system for secure assembly with compatible B-vent components
• Designed for Category I gas appliance venting applications
• Round rigid pipe form factor for straightforward installation in vertical and horizontal runs

Compatibility

Designed as an OEM-style replacement and new-installation component for B-vent systems serving Category I gas appliances with a 5-inch vent connector diameter.

Installation Notes

Installation must be performed by a licensed HVAC technician or qualified gas appliance installer in accordance with NFPA 54 (National Fuel Gas Code) and the appliance manufacturer's venting instructions. Shut off the gas supply and allow the appliance to cool completely before servicing or extending the vent system. Maintain required clearances to combustibles as specified by local building codes and the vent manufacturer. Inspect all twist-lock joints for full engagement before restoring appliance operation.
