Cleaning Brush GEKO G66706 — boiler and central heating tube brush Ø90/70 mm

GEKO G66706 is a tubular cleaning brush designed for maintenance of boilers and central heating (c.o.) systems. The brush features two working diameters — 90 mm and 70 mm — that allow access to flue tubes, heat exchanger passages and pipe interiors. Constructed for attachment to manual rods or compatible cleaning tools, this brush helps remove soot, ash and mineral deposits, supporting stable heat transfer and safer operation during routine servicing.

Advantages

The tubular design with dual diameters provides adaptability for different tube sizes without changing tools. Bristles are arranged to reach into narrow passages and dislodge accumulated soot and scale while allowing debris to be expelled along the tube. The brush is compatible with standard manual rods and most mechanical cleaning tools, enabling straightforward use during scheduled maintenance. Its shape and bristle density are intended to balance effective cleaning with minimal risk of damaging metal tube surfaces when used correctly.

Suitable for

• Cleaning flue tubes in solid fuel and gas boilers
• Removing soot and deposits from heat exchanger passages
• Maintenance of central heating pipes and chimneys
• Use with manual rods and compatible mechanical cleaning tools

Key specifications

• Working diameters: 90 mm and 70 mm
• Brush type: tubular cleaning brush for boilers and heating tubes
• Intended use: soot, ash and deposit removal from tubes and passages
• Compatibility: fits manual rods and common cleaning tool adapters
• Application environment: boiler flues, heat exchangers, central heating circuits

How to use

Attach the GEKO G66706 brush to a compatible manual rod or cleaning tool before inserting into the tube or passage to be cleaned. Start with the larger diameter where access allows, and switch to the smaller diameter for narrower sections. Operate with steady in-and-out motions and moderate rotational movement to dislodge soot and deposits. Periodically withdraw the brush and inspect debris; repeat passes until the tube walls appear clean. After use, remove remaining debris and store the brush dry to prevent corrosion of any metal components.

Usage recommendations

Use appropriate personal protective equipment, such as gloves and eye protection, and ensure the heating appliance is cold and disconnected from power or fuel supply before starting work. Avoid excessive force that could deform or damage tubes; if heavy corrosion or fragile surfaces are present, consider professional inspection. Regular use during scheduled maintenance intervals improves heat transfer efficiency and reduces risk of soot-related faults.
