Mill-rose 84214 Tapered Horsehair Boiler Brush 30 Inch 6 Pack

Product Description

The MILL-ROSE 84214 is a tapered horsehair boiler and flue brush designed for cleaning boiler tubes, flue passages, and heat exchanger surfaces where debris, soot, and scale accumulate over time. The tapered bristle profile transitions from 0.5 inches at the tip to 1 inch at the base, allowing a single brush to fit a range of tube diameters without swapping tools mid-job. At 30 inches in overall length, the brush reaches deep into boiler tubes and flue sections. Horsehair bristles provide effective scrubbing action on metal surfaces without causing scoring. Licensed HVAC technicians and boiler service professionals are the primary installers and users of this tool.

This brush is suited for routine maintenance and seasonal cleaning of residential and light commercial boilers, including water-tube and fire-tube configurations. It is used during annual boiler cleanings to clear combustion deposits from flue passages and tube interiors, helping maintain heat transfer efficiency and safe operation. The tapered design makes it practical for boiler tubes that vary slightly in inside diameter across a single unit. Each pack contains 6 brushes, supporting service fleets and shops that clean multiple units per route.

Installation Notes

Boiler and flue brushes are used by licensed HVAC technicians and boiler service professionals.
