This is the Atlas Copco packing part number 3121033600, Crowder SKU AC-3121033600. It keeps air or oil where it belongs inside the rock drill. Once it flattens or hardens, the machine loses pressure across the joint and performance falls off gradually rather than all at once.
The published breakdown lists it on the RH 658L/LS/LS-01 Rock Drill. It comes off the RH 658 L Surface Rock Drill.
Work through the rest of the assembly on the same breakdown, or start over from the full diagram library. It ships out of Denver, same day on in-stock orders placed before 4 PM ET.
