Ordering by number: this is 1280583523, which replaced the older number 03394, the American Pneumatic Tool O-ring – seal #2-118. 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.
You will find it on the diagram for the 115 Rock Drill. The complete machine is the APT 115 Pneumatic Rock Drill. Pull up the diagram and confirm the reference number for your serial before ordering.
