Part 770-534 is a gasket for 2.5‑gallon pressure pot tanks used on compatible ProFinish sprayers. It creates a leak‑tight seal between the lid and the tank body, preventing air loss and maintaining consistent material pressure. Replace when the original gasket is cracked, compressed, or no longer seals properly.

The Titan 770-534 Gasket (2.5‑gallon pressure pot) is a replacement sealing ring designed for the material tank on ProFinish TS40 and TS50 sprayers. It sits between the tank lid and the tank body, ensuring an airtight seal so that compressed air can push material to the spray gun without leaks or pressure drops.
Over time, the gasket can become compressed, hardened, cracked, or contaminated with dried material, leading to pressure loss, inconsistent spray patterns, or complete failure to pressurize. Replacing the gasket restores proper sealing and allows the pressure pot to maintain consistent working pressure.
| Airtight seal | Prevents compressed air from escaping between lid and tank |
|---|---|
| Pressure retention | Allows tank to reach and hold required working pressure |
| Material flow consistency | Ensures steady material delivery to the spray gun |
| Visible cracks / tears | Gasket material shows physical damage |
|---|---|
| Hardening or compression set | Gasket no longer rebounds; lid sits too deep |
| Air leaks around lid | Hissing sound or pressure drop during operation |
| Material contamination | Dried coating prevents proper sealing |

When replacing the pressure pot gasket, inspect these associated components to ensure reliable system performance.
Worn or bent clamps may not apply even pressure to the new gasket, causing persistent leaks.
A failing regulator can cause pressure fluctuations that mimic a bad gasket.
Inspect for leaks or stuck valves – they can vent pressure even if the gasket is good.
