Schaefer Brush 36405 Round Chimney Brush 5 Inch Steel Wire

Product Description

The SCHAEFER BRUSH 36405 is a round chimney brush designed for cleaning flue liners, chimney tiles, and smoke pipe interiors. It features a 5-inch diameter bristle head made from tempered steel wire, which provides the stiffness needed to dislodge creosote buildup, soot, and debris from masonry and metal flue surfaces. The brush connects to standard flexible or rigid chimney rods via a 1/4-inch NPSM male threaded fitting. Chimney sweeps and HVAC service techs use this brush for routine maintenance cleaning on residential and light commercial heating systems.

This brush suits round flue liners and smoke pipes with an interior diameter close to 5 inches. It is appropriate for use in wood-burning fireplaces, stoves, and gas appliance venting systems where periodic flue cleaning is required. The round profile matches circular tile liners, stainless steel inserts, and single-wall metal pipe. It is sold individually and is compatible with standard 1/4-inch NPSM threaded chimney rod systems available from most sweep supply vendors.

Compatibility

Designed as a rod-threaded chimney brush for round flue liners and smoke pipes sized at or near 5 inches in interior diameter, using systems with 1/4-inch NPSM threaded rod connections.

Installation Notes

Chimney brushes are installed by trained chimney sweeps or HVAC service technicians. Before cleaning, shut down and allow the connected appliance to cool completely, and verify the flue is free of obstructions such as bird nests or collapsed liner sections. Thread the brush securely onto rod sections before inserting into the flue to prevent separation during use. Work in a ventilated area and follow local codes and NFPA 211 guidelines for chimney inspection and cleaning intervals.
