Duravent 0612ADJ B-vent Round Adjustable Pipe 6x12 in

Product Description

The DURAVENT 0612ADJ is a round adjustable B-vent pipe section designed for natural-draft gas appliance venting systems. It accommodates a range of installation depths, adjusting from 3.5 inches to 10.5 inches in length within a nominal 6-inch diameter and 12-inch overall pipe body. This flexibility makes it well-suited for situations where fixed-length sections cannot bridge the gap between fittings cleanly. Licensed HVAC technicians and gas appliance installers use this type of component when running Type B vent systems for furnaces, boilers, and water heaters that require atmospheric venting.

This adjustable pipe section fits into residential and light commercial venting runs where a standard fixed-length section would leave an unworkable gap. It is particularly useful during retrofits or replacements where existing vent spacing does not align with standard pipe lengths. The 6-inch diameter is a common size in mid-to-large residential gas appliance installations, and the adjustable design reduces the need for field-cut sections or improvised fittings.

Key Features

• Adjustable length from 3.5 inches to 10.5 inches within a 12-inch nominal pipe body
• 6-inch diameter matches common residential and light commercial B-vent sizing
• Round pipe profile for standard Type B vent fittings and terminations
• Reduces field cutting and simplifies gap-bridging during installation or retrofit
• Designed for natural-draft atmospheric venting of gas-fired appliances

Compatibility

Designed as an OEM-style replacement and new-installation component for 6-inch Type B double-wall gas vent systems used with natural-draft gas appliances such as furnaces, boilers, and water heaters.

Installation Notes

Type B vent installation must be performed by a qualified HVAC or gas appliance technician in accordance with the appliance manufacturer instructions and the International Fuel Gas Code (IFGC). Always shut off the gas supply and allow the appliance and vent system to cool completely before servicing or adding vent sections. Maintain required clearances to combustibles as specified by the vent system manufacturer and local code. Do not mix Type B vent components from different manufacturers unless the system is listed and labeled for such use.
