Sealey 38pc Cleaning Brush Set - Injector Bore - Brass Steel Nylon - 8-19mm

The set includes brushes ranging from 8mm to 19mm in diameter.

The set includes brass, steel, and nylon brushes.

Yes, the included extension piece is a one-piece 150mm extension.

The brushes are generally compatible with common automotive cleaning solvents. However, it's best to check the chemical's compatibility with brass, steel, and nylon, and to rinse the brushes thoroughly after use.

The set comes with a convenient storage case to keep all 38 pieces organised and protected.

The brushes are designed to be screwed onto the extension. If a specific brush wears out, you would typically need to replace the entire brush head, often by purchasing a similar type of brush with a compatible thread.

The primary intended use is for cleaning and decarbonising areas with limited access, especially injector apertures before refitting.

Ensure the brush is screwed on securely. If the thread is damaged, try a different brush or a small amount of threadlocker for a semi-permanent fix on the extension piece if it's only used for one brush size.

Use less force, especially with smaller or softer brushes. Ensure you are using the correct brush material for the type of grime and surface. Steel brushes are for tougher jobs; nylon or brass may be more appropriate for lighter cleaning or sensitive areas.

While the extension provides added reach, some very deep areas may require alternative tools. Ensure you are using the correct angle of approach with the extension.
