0533573 Regulator Seal is a genuine OEM replacement seal for the pressure regulator on Titan PowrCoat and AirCoat sprayers. This seal (typically a diaphragm or gasket) creates a leak‑tight barrier between the regulator body and the fluid passage, ensuring accurate pressure control. A worn, torn, or hardened regulator seal can cause pressure loss, fluid leakage, and unstable spray performance. Replacing the seal restores proper regulator function and consistent output pressure.

The Titan 0533573 Regulator Seal is a critical sealing component inside the pressure regulator assembly. It creates a fluid‑tight barrier between the regulator's control chamber and the high‑pressure fluid passage, allowing the regulator to modulate output pressure accurately. This seal is often a diaphragm or a specially shaped gasket made of chemical‑resistant elastomer.
Over time, regulator seals can become torn, hardened, or compressed, leading to internal bypass of fluid. A failed seal results in pressure instability, inability to maintain set pressure, fluid leaking from the regulator body, or complete loss of regulation. Replacing the seal with an OEM component restores precise pressure control and prevents fluid leaks.
| Fluid isolation | Separates high‑pressure fluid from adjustment mechanism |
|---|---|
| Pressure sensing | Transmits pressure force to regulator spring for control |
| Leak prevention | Prevents external and internal fluid bypass |
| Pressure instability | Pressure surges or drops without knob movement |
|---|---|
| Fluid leak from regulator | Visible material seeping from regulator body seams |
| Inability to maintain set pressure | Pressure drifts continuously after adjustment |
| Visible seal damage | Torn, hardened, or deformed seal during inspection |
Part 0533573 is the OEM regulator seal for the following Titan sprayer models. Always verify with your machine's parts diagram.
| Brand / Model | Component |
|---|---|
| PowrCoat 630 | Regulator Seal |
| AirCoat 423 | Regulator Seal |
When replacing the regulator seal, inspect or replace these related regulator components.
The spring works with the seal to set pressure; replace if fatigued.
O‑rings on the stem and housing; replace during rebuild.
Inspect for cracks or damaged threads that could affect sealing.
