AirCoat part 0533429 is a gasket used in the fluid section of AirCoat 423 airless sprayers. This precision‑cut gasket provides a leak‑tight seal between mating surfaces, preventing fluid loss and maintaining system pressure. Replacing a worn, compressed, or damaged gasket restores proper sealing and helps avoid costly downtime.

The AirCoat 0533429 Gasket is a replacement sealing component designed for the fluid section of AirCoat 423 airless sprayers. It is installed between mating surfaces—such as the cylinder housing and the manifold or the pump body—to create a leak‑proof barrier that contains pressurized coating material.
Over time, gaskets can become compressed, hardened, or degraded due to chemical exposure, heat, and normal wear. A compromised gasket can result in external fluid leaks, pressure loss, and contamination of surrounding components. Replacing this genuine AirCoat gasket ensures a proper fit, correct sealing pressure, and reliable sprayer performance.
| Fluid containment | Prevents pressurized coating material from leaking out of the fluid section |
|---|---|
| Pressure maintenance | Helps maintain system pressure by sealing critical junctions |
| Component protection | Keeps contaminants out and protects adjacent parts from fluid damage |
| Visible leakage | Fluid seeping from between joined components during operation |
|---|---|
| Compression set | Gasket is flattened, hardened, or no longer resilient |
| Discoloration or cracking | Signs of chemical attack, heat damage, or physical deterioration |
| System disassembly | Always replace gaskets whenever a joint is opened for service |
AirCoat part 0533429 is a direct replacement gasket for the AirCoat 423 airless sprayer. Always consult your sprayer’s parts diagram to confirm the exact location and any related components.

When replacing the gasket, inspect these associated components to ensure a complete and reliable repair.
Check for corrosion or damage on the mating surfaces that could compromise the new gasket seal.
Inspect threads for damage; use new fasteners if original are corroded or stretched.
If the gasket is replaced during a fluid section overhaul, also replace packings and O‑rings.
