This is the Tamco/Toku inlet adaptor – NPT 3/8″ part number Y10106060, Crowder SKU TK-Y10106060. It joins the hose to the machine. Connection hardware gets dragged, dropped, and cross-threaded, so it is a common replacement.
Crowder’s breakdowns list this part on the THD 1100N Rock Drill and THD 1100U Rock Drill (CP9A). Worth matching the reference number on the diagram against your own machine before you order the same part number can sit in more than one position.
