MEECO'S RED DEVIL Pellet Stove Brushes are designed for cleaning pellet stove vent pipes (flues). The benefits of this design is a brush that follows the chimney and flue contours. The brush will easily reverse direction in the flue for easier cleaning. The brush easily negotiates angles and bends up to 90 degrees resulting in a more thorough cleaning with less effort. The pellet brush has a 1/4 x 20 thread. Attach the brush to Meeco's 4 ft. flexible extension rod for fast and easy use.
