Genuine SEALEY VS624 | Reverse Action Spark Plug Thread Chaser 12mm


SKU: 23701934743 Category: Tag:


Specially designed to repair damaged, deep-seated spark plug threads on modern engines. Unique design allows the tool to be passed through the plug thread into the combustion chamber, then expanded to the correct size starting on the inner, undamaged threads. Traditional thread restorers rely on luck for the restored and undamaged threads to align.
