Wrench "Standard Class" (39101)

I was skeptical at first, but this wrench fits the spray gun head perfectly and makes disassembly effortless. The internal mixture feature works exactly as described.

Finally, a tool that actually does what it's supposed to do. The internal mixture head came off my spray gun in seconds with zero stripping. Exactly the right fit for the job.

This wrench fits the spray gun head perfectly, no slipping at all. Made taking the internal mixture nozzle apart for cleaning way easier than using pliers.
