Copper injector brush purpose

The Brush Research JC-2 is a copper injector cleaning brush built for technicians and mechanics who need to remove carbon and residue from valve seats and injector bores. Its 1.350" major diameter targets the specific bore sizes found in many automotive cylinder heads and fuel-system components. It is not intended for general-purpose surface cleaning or for bores that differ from the stated diameter.

Installation and common issues

The brush mounts on a compatible hand tool or low-speed rotary driver and is worked through the bore with light pressure and solvent. Applying excessive force or high RPM can deform the copper bristles and reduce cleaning effectiveness, while insufficient reach leaves deposits at the bottom of the bore. Always verify bore diameter before use to avoid a loose or tight fit.

Sustained use behaviour

Under repeated cleaning cycles the copper fill resists loading and maintains cutting action longer than softer wire fills, though the bristles will gradually wear and shorten. The product carries a California Proposition 65 notice for chemicals known to cause cancer and reproductive harm, so wear appropriate gloves and ventilation during extended sessions.

Questions about this item

How can I verify the 1.350" major diameter brush is cleaning injectors effectively after setup?

What comes in the box with the JC-2 copper/injector cleaning brush and what must be purchased separately?

The package contains the 1.350" major diameter brush only; cleaning solvent, safety gloves and any required adapters are sold separately.

Select the JC-2 model with the 1.350" major diameter; it is the only variant listed for that specific valve size.
