## Description

The Sealey Reverse Action Spark Plug Thread Chaser offers a professional solution for repairing damaged spark plug threads on modern petrol engines. This innovative tool features a unique reverse action design that sets it apart from traditional thread restorers, which often rely on chance alignment between restored and undamaged threads. The tool passes through the plug thread directly into the combustion chamber, where it expands to the correct size and begins working on the inner, undamaged threads. This ensures precise alignment and reliable thread restoration every time. Available in M12 and M14 thread sizes to suit different engine specifications. A handy reference guide is built into the tool's application: for Denso, NGK and Bosch spark plugs, the first letter(s) of the plug code identifies the thread size, whilst for Champion brand plugs, the second letter(s) indicates the required thread size. Features and Benefits: &bull; Reverse action design for superior thread restoration accuracy &bull; Expands from within the combustion chamber for precise alignment &bull; Eliminates guesswork associated with conventional thread chasers &bull; Compatible with all major spark plug brands &bull; Professional-grade tool for workshop use
