Product Description
The IMPERIAL MFG GROUP USA INC BR0186 is a rectangular wire chimney brush built for cleaning rectangular flue tiles and chimney liners in residential and light commercial installations. The brush measures 8 inches by 12 inches and is constructed with a single spiral design using oil-tempered wire at 0.0286 inches in diameter. A 1/4-inch NPT male thread connection attaches the brush to standard flexible or rigid chimney rod systems. Licensed chimney sweeps and HVAC service technicians use this brush as part of routine flue maintenance and annual cleanings required by code.
This brush is suited for rectangular masonry chimney flues commonly found in wood-burning fireplaces and solid-fuel appliance systems. The 8-inch by 12-inch face covers a standard rectangular flue tile opening. The oil-tempered wire construction is appropriate for removing creosote deposits, soot, and debris from clay tile liners. It is typically deployed on residential service calls where a rectangular flue profile rules out the use of round brushes.
