Mill-rose 1218 Flue Brush 0.875 X 24 Inches All Stainless

Product Description

The MILL-ROSE 1218 is an all-stainless steel flue brush designed for cleaning narrow flue passages, vent connectors, and combustion exhaust channels in heating equipment. The brush head measures 0.875 inches in diameter with an overall working length of 24 inches, making it well suited for reaching deep into small-diameter flue tubes and firetubes. Constructed entirely from stainless steel — both the fill wire and the core — it resists corrosion from combustion byproducts and acidic condensate. HVAC technicians and boiler service techs rely on this type of brush for routine maintenance and pre-season cleaning work.

This brush is used in residential and light commercial heating applications where small-diameter flue tubes require periodic removal of soot, scale, and carbon deposits. Typical use cases include fire-tube boilers, water heaters, gas furnace heat exchangers, and similar combustion equipment with 0.875-inch flue passages. It is a standard hand tool used during annual maintenance, combustion analysis, and flue inspection service calls.

Key Features

• All-stainless steel construction resists corrosion from flue gases and acidic condensate
• 0.875-inch diameter head sized for small flue tubes and narrow vent passages
• 24-inch length provides reach into deep flue sections without extension
• Stainless fill wire maintains stiffness for effective scrubbing action
• Lightweight at 0.50 pounds for easy single-hand use during service

Compatibility

Designed as an OEM-style cleaning tool for heating equipment with 0.875-inch diameter flue tubes, vent connectors, or heat exchanger passages requiring brush cleaning.

Installation Notes

Always shut down the heating appliance and allow the flue and heat exchanger to cool completely before inserting any brush. HVAC technicians and boiler service professionals should follow applicable codes, including NFPA 54 and manufacturer maintenance guidelines, when performing flue cleaning. Use appropriate personal protective equipment when handling brushes contaminated with combustion byproducts. Do not force a brush into a passage smaller than the rated brush diameter, as this can damage flue liners or heat exchanger surfaces.
