Injector Socket 21mm Ford Duratorq Diesel 1/2in Drive Engine

A 21mm injector socket made for work on Ford Duratorq diesel engines, with a 1/2in drive for use with standard ratchets and breaker bars. The cut-away window helps with alignment during fitting and removal, making it easier to position the socket correctly on the injector.

Used for injector removal and installation during engine servicing, repair work and vehicle maintenance, this type of socket is aimed at mechanics, garages and experienced DIY users working on compatible diesel engines. It is particularly useful when access is tighter around the injector area and a standard socket is not suitable for the job. For regular servicing work, having the correct injector tool close to hand helps keep the job more straightforward.

Made from chrome molybdenum steel, the socket is built for the demands of workshop use where strength matters. The 21mm size suits the stated application, while the 1/2in drive makes it easy to pair with commonly used drive tools already in the box. The alignment window is a practical feature when working in awkward engine bays, helping you see placement more clearly before applying force. Compatibility is listed against OEM reference 303-677, which is useful when checking against tool requirements before starting the job.
