Plug Tool
Mack

The Plug Tool is a purpose-built instrument for installing and removing plugs in tight or recessed ports across heavy-duty equipment. Its design emphasizes control and leverage, enabling clean seating of plugs without damaging threads or seals. This tool minimizes the risk of cross-threading and thread damage during field service, which translates into fewer leaks and longer service intervals between replacements. Its compact profile makes it suitable for work in cramped engine compartments or compact hydraulic manifolds, where conventional tools struggle. The Plug Tool supports consistent plug installation practices, reducing the chance of inadvertent over-tightening or under-tightening that could compromise system integrity. Source One Parts Center.
