This is the Chicago Pneumatic O-Ring part number H0364441, cross-referenced to 3310104833, Crowder SKU CP-H0364441. It keeps air or oil where it belongs inside the breaker. Once it flattens or hardens, the machine loses pressure across the joint and performance falls off gradually rather than all at once.
It appears on the CP 0117 0117S Paving Breaker breakdown. 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.
