Expert Verdict — Reviewed by the SuperArbor Pro Desk
Always pair the storm collar with the correctly sized pipe flashing, sizing both to the B-Vent pipe diameter. Bed the inner edge in high-temp silicone so the seal survives flue gas temperatures. Choose the 8 in. size only for 8 in. pipe; oversizing a collar prevents a proper seal.
Use only high-temperature silicone sealant near vent pipe, and take appropriate roof-work fall-protection precautions during installation.
Complete your DuraVent B-Vent roof penetration with the correctly sized aluminum storm collar.
