Titan part 245-012 is a pump cylinder used in the fluid section of compatible airless sprayers. This precision‑honed cylinder houses the piston and packings, providing the bore in which the piston reciprocates to generate pressure. A scored, worn, or corroded cylinder can cause loss of pressure, excessive packing wear, or fluid leakage past the piston. Replacing the cylinder restores proper pump efficiency and extends equipment life.

The Titan 245-012 Pump Cylinder is a genuine OEM replacement cylinder (also called a pump barrel or liner) for the fluid section of Admiral, Commander, and Hydra series airless sprayers. It provides the precision‑machined bore in which the piston reciprocates, sealed by upper and lower packing sets.
Over time, the cylinder bore can become scored from abrasive particles, corroded from water left in the pump, or worn oversize from normal use. A damaged cylinder causes poor pump performance: loss of pressure, rapid packing failure, fluid bypass, and difficulty priming. Replacing the cylinder (along with new packings) restores original pump output and efficiency.
| Houses the piston | Provides smooth bore for reciprocating piston |
|---|---|
| Seals with packings | Works with packings to prevent fluid blow‑by |
| Generates pressure | Creates high pressure as piston compresses fluid |
| Wear surface | Sacrificial component that protects pump housing |
| Loss of pressure / output | Pump cannot reach or maintain operating pressure |
|---|---|
| Rapid packing failure | Packings wear out quickly, causing external leaks |
| Visible bore damage | Scratches, scoring, pitting, or corrosion inside cylinder |
| Loss of prime | Pump struggles to prime, indicating blow‑by |
