Description
US PRO Tools 6-Piece 3/8-Inch Drive Diesel Injector Line Socket Flexi Head Wrench Set (12mm – 19mm) – Model 5642
Product Overview
The US PRO Tools (Model 5642) is a professional 6-piece specialized wrench set engineered specifically for removing and tightening high-pressure diesel fuel injection lines on modern common-rail and commercial diesel engines. Featuring a flexible swiveling head design and a slotted/crowfoot socket profile, this set allows technicians to bypass rigid fuel lines and reach awkward, restricted union nuts on fuel pumps, common-rail rails, and injectors without rounding off soft fittings.
