0533556 Spring Regulator is a genuine OEM replacement spring for the pressure regulator on Titan AirCoat sprayers. This precision spring provides the calibrated force that determines the outlet pressure setting when the regulator adjustment knob is turned. A weak, broken, or fatigued regulator spring leads to unstable pressure, difficulty adjusting pressure, or complete loss of regulation. Replacing the spring restores accurate pressure control and consistent spray performance.

The Titan 0533556 Spring Regulator is an internal component of the pressure regulator assembly. It provides the counter‑force against the regulator diaphragm, allowing the adjustment knob to set the desired fluid outlet pressure. When the knob is turned, it compresses or decompresses this spring, changing the force applied to the diaphragm and thereby controlling pressure.
Over time, regulator springs can lose their preload due to metal fatigue, corrosion, or repeated compression cycles. A weakened spring causes poor pressure stability, inability to reach maximum pressure, or drifting pressure settings. Replacing the spring with an OEM part restores precise, repeatable pressure regulation.
| Pressure setting | Provides calibrated resistance to set outlet pressure |
|---|---|
| Stable regulation | Maintains consistent pressure despite flow variations |
| Adjustment range | Allows smooth pressure change from minimum to maximum |
| Pressure instability | Pressure fluctuates without knob movement |
|---|---|
| Cannot reach max pressure | Fully tightened knob gives insufficient pressure |
| Drifting pressure | Pressure slowly drops or rises after setting |
| Broken / deformed spring | Visible damage during regulator disassembly |
Part 0533556 is the OEM regulator spring for the following Titan sprayer model. Always verify with your machine's parts diagram.
| Brand / Model | Component |

| AirCoat 423 | Spring Regulator |
When replacing the regulator spring, inspect or replace these related regulator components.
The spring pushes against the diaphragm; a torn diaphragm will also cause pressure issues.
Includes o‑rings and backup rings; replace when rebuilding the regulator.
Inspect for stripped threads or damage that could affect spring compression.
