DuraVent 4 Inch B-Vent Pipe Oval to Round Adapter

DuraVent gives you everything you need to construct a flue system that fits your home. The DuraVent B-Vent Pipe Oval to Round Adapter transitions your system from oval B-vent to standard round B-vent pipe as it moves through your home. The pipe locking system creates an airtight seal when connecting DuraVent chimney pipe lengths, ensuring no smoke leakage. A clever design reduces expansion noises and helps avoid your chimney system's annoying popping and creaking as it heats and cools.
