Cylinder Seal is the American Pneumatic Tool service part carried under part number 1280582664, listed as 17950 before the renumbering. 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.
Crowder’s breakdowns list this part on the 140 Paving Breaker and 140 Paving Breaker – Former Construction. The tool itself is the APT 140 Pneumatic Paving Breaker. Check it against the reference number on the diagram first; serial breaks change what fits.
