6" Dia*7.87" H Round Chimney Cleaning Kit Brush, Fits Standard 1/4" NPT Rod

1/4 Inch NPT Fittings: Our chimney cleaning brush has a 1/4" male pipe thread and is compatible with a standard 1/4" NPT extension rod. It is not compatible with Midwest Hearth products. Please verify your rod thread type before ordering | High-quality Brush: The stiff brush is made of high-quality polypropylene material, which can effectively clean coal and soot in metal furnace pipes, flues, and chimneys, and is not easy to scratch the inner surface of the flue | Double-spiral Construction: The heavy-duty double-spiral stem is used to fix the bristles more firmly, so you don't have to worry about the bristles falling off when you use it, and it can be used for a long time | Better Effect: Use the fiberglass chimney cleaning brush to clean the chimney duct, saving money, time, and effort. We recommend cleaning your chimney at least once a year, or more often if you use your chimney a lot | Easy to Use: Just align the joint of the chimney brush with the joint of the extension rod and tighten it. You can determine the number of extension rod connections based on the length of the pipe you want to scrub. It can be easily disassembled and cleaned after use for the next use
