Product Description

DuraVent 3" B‑Vent Storm Collar (manufacturer model 3BVSC, UPC 662492957165) is the formed metal finishing collar that installs over a 3" DuraVent Type B (BV) gas‑vent pipe above the roof flashing to divert water and complete the weather‑tight seal; sold individually (each). The part is listed by DuraVent and resellers under the 3BVSC/810017804 stock numbers and is specified for use with DuraVent BV gas vent systems; installers seal the collar’s upper inner edge with high‑temperature, non‑hardening sealant where it meets the pipe. Current online offers checked Sep 28, 2026 show a wide retail spread (example resellers at ~$3.39 each up to marketplace listings near $18.67 each), so a competitive local resale price for Dayton, IA 50530 that balances margin and competitiveness would be $9.99 each (this undercuts many marketplace markups while leaving room for local pickup/handling costs).
