| Detail | Technical / Commercial Information |
|---|---|
| Product Overview | OEM Titan piston used in the high-pressure fluid regulator assembly on AirCoat 423 and AirCoat 620 spray systems. Part number cross-references to 533537. |
| Function | The piston is an internal component of the regulator assembly that responds to fluid pressure and spring force to control system pressure. When the regulator is adjusted, the spring compresses against the piston, which moves to open or close the regulating valve. A worn, scored, or damaged piston can cause pressure instability, erratic regulation, or complete loss of control. |
| Industrial Applications | Professional sprayer repair, regulator assembly servicing, pressure control system maintenance, and preventive maintenance of AirCoat 423 and AirCoat 620 spray systems. |
| Compatible Titan Machines | AirCoat 423; AirCoat 620. |
| Accurate Part Number | 0533537 Piston (cross-references to 533537). |
| Compatible Parts & Assemblies | High-pressure fluid regulator assembly, regulator housing (0533534), regulator spring (0533556), bar (0533529), and threaded bar (0533536). |
| Related Parts Commonly Serviced Together | Regulator spring, O-rings, seals, and copper gaskets used in the regulator assembly. |
| Common Problems Solved | Pressure instability, difficulty maintaining consistent set pressure, regulator adjustment not responding properly, erratic spray performance, and loss of pressure control caused by a worn or damaged piston. |
| Use with Coating Systems | Supports AirCoat systems used by painting contractors, wood finishers, and industrial finishing professionals. The AirCoat 423 system delivers up to 2670 psi with a 23:1 pump ratio. |
| OEM & Brand Information | Genuine Titan OEM component designed for correct fitment in AirCoat series spray systems. The piston is a critical internal component of the regulator assembly. If you experience pressure instability, difficulty maintaining a consistent set pressure, or erratic regulator response, inspect the piston for signs of wear, scoring, or damage. When replacing the piston, also inspect the regulator housing bore and replace all O-rings and seals. Use genuine Titan components to ensure proper fit and reliable pressure control. |
| Commercial Benefits | Restores precise pressure regulation, ensures consistent spray performance, maintains system integrity, and extends equipment service life. |
