Oil Gallery Brush - 5/8" X 34"

You can't have a clean engine with just a hot tank and an air hose with water. You need something to take out the old metal chips, the grinding compounds, the sludge and the dirt from the parts you can't see - the oil passageways. BRM uses the finest-quality high-density 6-12 Nylon in their nylon Oil Gallery Brushes.
