Titan part 0533618 is a copper gasket used to create a high‑pressure seal between mating surfaces on the AirCoat 423 airless/air‑assisted sprayer. Copper gaskets are soft, conformable, and resistant to high temperatures and pressures, making them ideal for fluid section connections, valve assemblies, or regulator ports. A crushed, leaking, or missing copper gasket can cause fluid leakage, pressure loss, or air ingestion. Replacing with the OEM copper gasket ensures a leak‑tight seal and reliable system performance.

The Titan 0533618 Copper Gasket is a genuine OEM sealing component for the AirCoat 423 airless/air‑assisted sprayer. Made from soft, annealed copper, it is designed to compress between two flanged or threaded fittings, creating a leak‑proof seal capable of withstanding high fluid pressures and temperatures.
Copper gaskets are typically used in fluid section connections, pressure transducer mounts, regulator assemblies, or high‑pressure hose fittings. Over time, a copper gasket can become crushed beyond reuse, work‑hardened, or damaged during disassembly. A leaking or missing gasket causes fluid seepage, pressure drop, and potential safety hazards. Replacing with OEM Titan 0533618 ensures a proper seal and reliable, leak‑free operation.
| Seals high pressure | Creates leak‑tight seal under extreme conditions |
|---|---|
| Conforms to surfaces | Soft copper fills microscopic irregularities |
| Heat resistance | Withstands high temperatures without degrading |
| Chemical compatibility | Resistant to paints, solvents, and cleaning agents |
| After any disassembly | Copper gaskets are single‑use; always replace |
|---|---|
| Visible crush or deformation | Gasket no longer has original thickness |
| External leakage | Fluid seeps from the joint |
| Corrosion / pitting | Gasket surface is damaged or corroded |

When replacing a copper gasket, inspect these associated components.
Check for nicks, burrs, or warping that could prevent sealing.
Inspect threads for damage; clean before reassembly.
Use a torque wrench to avoid overtightening.
