This is American Pneumatic Tool part number 1280583516, previously 03373 air inlet swivel nut Ass’y, stocked at Crowder Supply as APT3373. 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 180 Paving Breaker, and on 4 other machines. Check it against the reference number on the diagram first; serial breaks change what fits.
If you need the parts around it, the full diagram library has the full breakdown library, and the APT lineup covers the machines themselves. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
