Schaefer Brush 76235 Boiler Furnace Fiber Brush

Product Description

The SCHAEFER BRUSH 76235 is a fiber boiler and furnace cleaning brush designed for sweeping flue passages, heat exchanger tubes, and combustion chamber walls. The brush head measures 2 inches in diameter with 6-inch fiber bristles that conform to tube and flue interior surfaces to dislodge soot, scale, and debris without scoring metal. A standard wood handle brings the overall assembled length to 42 inches, giving technicians the reach needed to service mid-depth boiler flue sections. HVAC and boiler service technicians keep this brush as standard kit for routine combustion-system cleaning.

This brush is suited for residential and light commercial boiler and furnace maintenance. It is commonly used during annual tune-ups and heat exchanger inspections to clean fire-side tube surfaces, flue passages, and combustion deposits. The 42-inch overall length makes it practical for accessing deeper flue sections without extension rods in many standard residential boiler configurations. The fiber bristle construction is appropriate for use on steel and cast-iron flue and boiler surfaces.

Installation Notes

This brush is installed and used by licensed HVAC technicians and boiler service professionals during scheduled maintenance or pre-season inspections. Always shut down the boiler or furnace and allow all surfaces to cool completely before inserting any cleaning tool into flue or heat exchanger passages. Verify that the flue and combustion chamber are fully de-pressurized and isolated before beginning cleaning. Follow local codes and the equipment manufacturer service procedures when performing combustion-system maintenance.
