Product Summary

National Chimney does not crimp our reducer/increaser so you can choose which end needs crimping for your application. Reducer/Increasers are available in 304 (wood and wood pellet applications) or 316 (all fuel applications). Choose from a 3 piece/tapered design for maximum flow or our plug style for tight spots.
