Injector Washer Removal Tool 85mm Copper Seal Slide Hammer

An injector washer removal tool used for pulling burnt-in copper sealing washers from the injector shaft during diesel engine servicing. Built around an 85mm long conical tip and slide hammer action, this puller tool gives a controlled way to remove stubborn seals without prising at them by hand.

Used for diesel injector work on BMW, Mercedes-Benz and PSA models, this tool is suited to servicing jobs where old copper seals have become stuck in place. It is useful during injector replacement, seal changes and general vehicle maintenance, especially when access is tight and the washer needs lifting out cleanly before refitting. For garages, mobile mechanics and experienced DIY users, it helps make injector seat preparation more straightforward before new seals are installed.

The conical tip is exchangeable and works with injector sealing rings with an internal diameter from 4mm to 16mm, covering a practical range for common diesel applications. An 840g sliding weight gives enough force for repeated extraction work while still allowing controlled movement, and the ergonomic handle gives a steadier grip when working down the injector bore. Because the tool is intended for removing burnt-in washers from the shaft, it also helps reduce the chance of damage to the cylinder head compared with improvised removal methods. That makes it a sensible option for regular servicing where clean removal matters.
