PRB-80 : Pushrod Cleaning Brush
Clean the inside diameter of your pushrods with this brush. Will fit pushrods as small as 0.080" ID. 12" long overall. NOTE: It's important to clean the insides of your pushrods when rebuilding an engine. If not the cleaning the ID of the pushrods is like putting your dirty clothes on after a bath; you risk contaminating all of the work you've done. You need the pushrod brush because the ID is so small it's unlikely your hot tank will be able to get the gunk out.
