Mill-rose BM-70255 Blue Monster Copper Cleaning Brush

Product Description

The MILL-ROSE BM-70255 is a dual-end copper cleaning and deburring brush designed for preparing 1/2 inch and 3/4 inch copper tubing and fittings before soldering or pressing. The 6 inch brush head removes oxidation, flux residue, and burrs from both the outside diameter of tubing and the inside of fittings, leaving a clean mating surface for a reliable joint. At 7.5 inches overall length, it gives plumbers a comfortable grip during prep work. This is a standard hand tool carried by plumbing and HVAC technicians who work with copper distribution and refrigerant piping regularly.

This brush is used in residential and light commercial plumbing and HVAC applications wherever copper tubing and fittings require surface preparation. Common install scenarios include potable water supply lines, hydronic heating loops, and refrigerant line sets. The two-in-one design cleans both 1/2 inch tubing OD and 3/4 inch fitting ID without switching tools, making it practical on tight job sites where minimizing hand tools speeds up rough-in and trim-out work.

Key Features

• Dual-end design cleans 1/2 inch copper tubing OD and 3/4 inch copper fitting ID in one tool
• Removes oxidation and burrs for a clean bonding surface ahead of soldering or brazing
• 7.5 inch overall length provides a secure, full-hand grip during use
• 2 inch overall width keeps the tool compact for work in confined spaces

Compatibility

Designed for use with copper fittings and copper tubing in 1/2 inch and 3/4 inch sizes, as specified by the manufacturer.

Installation Notes

This tool is used by licensed plumbers and HVAC technicians during pipe preparation before soldering, brazing, or pressing copper joints. Shut off the water supply or refrigerant system and relieve all pressure before cutting and prepping tubing. Work the brush in a consistent rotational motion to ensure even cleaning around the full circumference of the tubing OD or fitting ID. Follow applicable codes such as the IPC or IFGC for joint preparation requirements on potable water and gas piping systems.
