Valve Cleaning Brush

The Brush Research JC-3 is a copper injector cleaning brush with a 1.500 inch major diameter. It is designed for automotive technicians and maintenance personnel who need to remove deposits from valve and injector passages. The tool addresses carbon build-up that can restrict flow and affect engine performance. It is a new item supplied directly by the manufacturer.

California Proposition 65 Notices

This product carries two distinct California Proposition 65 warnings. The first indicates the presence of a chemical known to the state to cause cancer. The second warns of a chemical known to cause birth defects or other reproductive harm. These notices inform the user about material content so appropriate handling precautions can be taken during use.

Copper Construction and Sizing

The copper brush material provides a softer cleaning action compared to steel, reducing the risk of damaging sensitive injector seats or valve guides. The 1.500 inch major diameter determines the specific bore sizes this tool can effectively service. Direct manufacturer shipping means the item arrives in original packaging without intermediate handling.

Questions about this item

When will the copper bristles on this JC-3 brush need replacement?

The copper bristles wear down with repeated injector cleaning; replace the brush when the 1.500" major diameter no longer contacts the valve seat evenly.

What limits continuous use of this copper injector brush?

The soft copper filament is the limiting factor — it deforms under sustained pressure and loses cleaning effectiveness before the steel stem shows wear.

Does the brush generate heat or require power during all-day cleaning jobs?

The brush is a hand tool with no motor or electrical connection, so it produces no heat and draws no power during extended use.
