Duravent 05ARF B-vent Adjustable Roof Flashing 5 Inches

Product Description

The DURAVENT 05ARF is an adjustable roof flashing designed for 5-inch B-vent gas appliance venting systems. It creates a weathertight seal where the vent pipe exits through the roof deck, accommodating roof pitches from flat up to 6/12. This flashing is a critical component in any B-vent installation, preventing water intrusion at the roof penetration point. Licensed HVAC technicians and gas appliance installers working on natural gas or propane heating equipment will encounter this fitting on standard residential and light commercial venting jobs.

This flashing is suited for residential and light commercial applications where Type B double-wall gas vent pipe passes through a sloped or flat roof. It is sized for 5-inch B-vent pipe and handles the range of common roof pitches found in typical residential construction. It is typically used with gas furnaces, boilers, water heaters, and other Category I gas appliances that require Type B venting.
