Swivel Ass’y, American Pneumatic Tool part number 1280583521, listed as 03389 before the renumbering, listed at Crowder Supply as APT3389. It makes the air or hydraulic connection to the rock drill. Thread and sealing-face condition here is the difference between full pressure at the tool and a slow leak nobody notices.
It is called out in the parts diagram for the 155 Rock Drill and CP 1260SPDR Spike Driver, and on 3 other machines. Check it against the reference number on the diagram first; serial breaks change what fits.
Everything else on that machine is one page away on the parts diagram hub; complete tools are on the American Pneumatic Tool range. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
