Ordering by number: this is R110215 (also carried as 3310104271), the Chicago Pneumatic cylinder seal. It carries the piston and the port timing for the breaker. Bore wear is gradual, so it is usually diagnosed by falling performance rather than a breakdown.
It appears on the CP 1210 S SVR Paving Breaker and CP 1210 1210S 1210SVR Paving Breaker breakdown. Compare it to the reference callout on the diagram to be sure it is the position you need.
The rest of the assembly is on the same breakdown, and every diagram we publish is indexed on the full diagram library. Ships from our Denver warehouse; in-stock parts ordered by 4 PM ET go out the same day.
