SP-25 PISTON (PDB13008) B-30

SP-25: This is almost certainly a serial number, model number, or specific variant code for this particular piston. It could indicate:

• A specific series or design revision (e.g., "SP" for "Spare Part").
• A compatibility indicator for a certain machine model.
• An internal tracking number used by the manufacturer.

PISTON: This clearly identifies the component. A piston is a fundamental part of many engines, pumps, compressors, and hydraulic/pneumatic systems. It's a reciprocating (moving back and forth) component that transfers force created by pressure (e.g., in an engine cylinder) or exerts force to create pressure (e.g., in a pump or compressor).

(PDB13008): This is highly likely a Part Drawing Number (PDN), Bill of Materials (BOM) number, or a specific manufacturing code.
