Brass adapter threaded M 10x1 (f) to 1/8" NPT (m)

Certain Milwaukee 18v grease guns ship with a hose that has a metric 10x1 working end. If you try to replace the coupler and the new coupler does not fit, you need this adapter

NOT ALL MILWAUKEE GUNS ARE AFFECTED. Unfortunately Milwaukee has not said which batches ship with metric hoses and which ship with NPT ends, as they are supposed to. You will need to check the threads or attempt to replace the coupler to know which hose you have.
