The Sealey Diesel Injector Window Socket Set (SX0401) is an essential toolkit addition for professional automotive technicians and advanced DIY mechanics tasked with servicing diesel engines. Designed for the efficient removal and installation of fuel injectors, this set allows users to work around existing wiring harnesses without disconnection, though the open-sided design requires careful handling to prevent socket spreading under extreme torque.

No, this set covers common sizes (21mm, 22mm, 27mm, 28mm), but it may not fit every specialized or proprietary injector nut size on the market.
While made of durable Chrome Molybdenum, we recommend using hand tools or a torque wrench to prevent premature deformation of the open side.
The set is designed for use with a standard 1/2-inch square drive.
These are specifically designed for diesel injectors, which typically have different hex sizes and clearances compared to petrol variants.
Store them in a cool, dry place, ideally on a socket rail or in a foam-lined tool box to protect the precision-cut openings.
Ensure the socket is pushed fully down onto the hex surface and verify the correct size is being used.
Ensure the 'window' of the socket is oriented to clear the fuel line or wiring harness obstacle.
Check if the injector nut is rounded or damaged; a loose fit can lead to tool deformation under load.
To use the set, match the required hex size to the injector nut and ensure your 1/2-inch square drive ratchet or torque wrench is properly attached. Always verify that the injector nut is clean and free of debris to ensure a snug fit.
