| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan piston used in the air motor assembly of AirCoat 423 and AirCoat 620 spray systems. Converts compressed air into linear mechanical motion to drive the fluid pump. |
| Function | Converts compressed air into linear mechanical motion. The piston reciprocates within the motor cylinder, driving the fluid pump to create the pumping action. A properly functioning piston is essential for efficient conversion of compressed air into mechanical motion. The piston rod connects the piston to the displacement rod of the fluid pump, transmitting force to move coating material. Worn or damaged pistons can cause loss of power, erratic operation, or failure to cycle properly. |
| Replacement Indicators | Signs that replacement is needed include visible scoring or damage on the piston surface, loss of power or erratic air motor operation, failure to cycle properly, air leakage past the piston, and during routine air motor servicing. |
| Service Guidance | If the air motor exhibits signs of power loss, erratic operation, or failure to cycle, the piston should be inspected for wear or damage. When replacing the piston, inspect the cylinder bore for scoring or damage. The motor service kit (0533924) includes this piston along with other wear components for complete air motor servicing. |
| Industrial Applications | Professional finishing, cabinet and furniture painting, wood and metal finishing shops, and industrial coating applications. |
| Compatible Models | AirCoat 423, AirCoat 620. |
| Accurate Part Number | 0533382 Piston. |

| OEM & Brand Information | Genuine Titan OEM component designed for correct fitment in compatible AirCoat systems. |
| Commercial Benefits | Restores proper air motor compression, prevents power loss and erratic operation, and maintains reliable pump drive performance. |
The 0533382 Piston is a genuine OEM component for compatible AirCoat spray systems. Over time, the piston can become worn, scored, or damaged due to normal operation, lack of lubrication, or contamination. A damaged piston can cause the air motor to lose power, operate erratically, or fail to cycle properly, which affects the performance of the fluid pump and the quality of the spray finish. If the air motor exhibits signs of power loss, erratic operation, or failure to cycle, the piston should be inspected for wear or damage. The motor service kit (0533924) includes this piston along with other wear components for complete air motor servicing. When replacing the piston, inspect the cylinder bore for scoring or damage. This part is not listed as a component for the Commander air-powered airless sprayer. Refer to your product manual for detailed information about this component.
