The Dewey 37mm/40mm Replacement Brush is a replacement brush set from Dewey (listed under part number B3740), sized to fit an existing Dewey cleaning rod or kit rather than requiring a full new purchase. Brushes wear out well before the rod or handle they’re mounted on, and replacing just the brush is both cheaper and faster than buying an entire new kit. This set keeps a cleaning kit already in service fully stocked for future use. It’s the kind of item worth keeping a spare of, since a worn-out brush is easy to overlook until it’s needed mid-cleaning.
