Mill-rose 1258 Stainless Steel Boiler Brush 3/8 in 36 in

Product Description

The MILL-ROSE 1258 is a single-spiral flue and boiler tube brush built for cleaning combustion system passageways in heating equipment. The brush head is 3 inches long with a 3/8-inch diameter and stainless steel bristles that hold up to repeated contact with carbon deposits, scale, and corrosion inside boiler tubes, flue passages, and burner nozzles. The full assembly reaches 36 inches in length, giving technicians the reach needed to clean deep tube sections without extensions. Each handle is labeled with individual UPC identification for easy inventory tracking in a service van or shop.

This brush is suited for HVAC and plumbing technicians servicing residential and light commercial heating systems. It is designed for use on boilers, burners, fan tubes, flue passages, and nozzles where regular maintenance is required to maintain combustion efficiency and safe operation. The 1/2-inch to 3/4-inch loop size accommodates standard fitting connections during use. Brushes are sold in packs of 12, making this a practical stock item for service companies performing seasonal boiler cleanings or scheduled maintenance routes.

Installation Notes
