Buying Guide
What size is needed? Measure your pipe or flue diameter and choose a damper that matches (commonly 4″ or 6″).
Material and finish matter. Cast iron provides heat resistance and durability; look for a high-temperature coating that resists rust and warp.
What type of system? Dampers come in window or throat styles. Use a stove pipe damper for pipes and a throat damper for fireplaces. Choose the right one for your installation location.
Best for control. If precise airflow is required, pick a damper with a simple, solid mechanism and a reliable seal to minimize drafts when closed.
Installation considerations. Some dampers fit standard pipe sizes and can be swapped in without major modifications; others may require adapters or professional installation.
