UNIPAK UNIBRUSH Ø18 mm for copper pipe – tube brush for 18 mm copper tubing

UNIPAK UNIBRUSH Ø18 mm for copper pipe is a cylindrical tube brush designed to clean and deburr the internal surfaces of 18 mm copper tubing. Engineered for use before soldering or mechanical joining, the brush removes oxidation, solder residues and loose debris to improve joint quality and ensure consistent flow through the pipe. The compact Ø18 mm profile fits standard 18 mm copper pipe inner diameters and is suitable for use by plumbers, HVAC technicians and refrigeration specialists.

Advantages

The brush provides efficient removal of scale and soldering residues without damaging the pipe wall, promoting stronger soldered or brazed joints. Its cylindrical shape ensures even contact with the inner surface of 18 mm copper tubing for uniform cleaning. The tool is compact and easy to handle, enabling quick preparation of short pipe lengths and fittings in tight working spaces. By removing contaminants before assembly, the brush helps reduce the risk of leaks and maintains unobstructed flow.

Suitable for

• Cleaning and deburring 18 mm copper pipe before soldering
• Preparing pipes for brazing, compression or mechanical fittings
• Plumbing installations and repairs in residential and commercial settings
• HVAC and refrigeration maintenance where copper tubing is used

Key specifications

• Brush diameter: 18 mm (cylindrical profile designed for 18 mm copper tubing)
• Intended material: copper pipe inner surface cleaning and deburring
• Primary function: removal of oxidation, solder residues and loose debris
• Application area: plumbing, heating, ventilation, air conditioning and refrigeration
• Form factor: tubular brush for insertion into pipe bore

How to use

Insert the UNIPAK UNIBRUSH Ø18 mm into the end of the copper tube and rotate the brush by hand or with a compatible driver to scrub the inner wall. Move the brush along the tube length and into fittings as needed to reach all surfaces that will be joined. After brushing, remove any loosened particles by blowing out the pipe with compressed air or wiping with a clean cloth. Inspect the cleaned area to ensure all oxidation and debris have been removed prior to flux application and soldering or assembly.

Usage recommendations

Use appropriate personal protective equipment such as gloves and eye protection when cleaning pipes. For best results, combine brushing with a suitable flux and ensure surfaces are dry and free of oil before soldering. Replace the brush when bristles show excessive wear to maintain effective cleaning performance.
