Duravent 08BVSC Storm Collar 8 Inch Galvanized Steel

Product Description

The DURAVENT 08BVSC is a galvanized steel storm collar designed for use with 8-inch B-vent pipe systems. It seats around the flue pipe at the roof penetration point, sealing the gap between the pipe and the roof flashing to prevent water intrusion. Constructed from galvanized steel, this collar resists corrosion and weathering in exposed rooftop conditions. Licensed HVAC technicians and plumbers install this component as part of a code-compliant B-vent termination. At 11.375 inches outer diameter and 1.5625 inches in height, it provides reliable coverage around standard 8-inch vent pipe.

This storm collar is suited for residential and light commercial gas appliance venting installations where an 8-inch B-vent pipe exits through a pitched or flat roof. It is installed after the roof flashing is in place, sliding over the vent pipe and sealing against the flashing cone to complete the weathertight roof penetration. Typical applications include natural gas and propane furnace, boiler, and water heater venting that uses double-wall B-vent pipe assemblies.

Key Features

• Galvanized steel construction provides corrosion resistance for outdoor roof exposure
• Sized for 8-inch B-vent pipe for a secure, snug fit at the roof flashing
• 11.375-inch outer diameter provides broad coverage around the flashing cone
• Low-profile 1.5625-inch height fits tight roof clearance situations
• OEM-style replacement suitable for standard B-vent roof termination assemblies

Compatibility

Designed as an OEM-style replacement storm collar for 8-inch B-vent venting systems using standard double-wall vent pipe roof termination assemblies.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with the International Fuel Gas Code and the appliance manufacturer's venting instructions. Shut down and allow the appliance and flue pipe to cool completely before beginning any roof penetration work. The storm collar slides over the vent pipe and seats against the roof flashing cone, and should be sealed with a high-temperature silicone or roofing sealant appropriate for metal flashing applications. Always verify local code requirements for flashing and collar installation before completing the termination.
