Titan part 449-605 is a tank gasket used to create a leak‑proof seal between the paint tank and the sprayer body. It prevents fluid leakage, maintains proper pressure for priming and spraying, and helps keep the pump primed. Replacing a worn or damaged gasket restores reliable sealing and prevents messy leaks on compatible Titan PowrLiner, PowrTwin, and PowrTex units.

The Titan 449-605 Tank Gasket is a critical sealing component that fits between the paint tank and the sprayer body. It prevents paint from leaking during operation, ensures proper priming, and maintains consistent pressure for airless spraying. A reliable seal is essential for efficient performance and a clean work environment.
Over time, the gasket can become compressed, hardened, cracked, or deformed due to chemical exposure and normal wear. A failing gasket may cause leaks, loss of prime, or erratic spray patterns. Replacing it with this genuine Titan part restores a secure seal and reliable operation.

When replacing the tank gasket, it's a good practice to inspect these related components to ensure a complete repair.
A warped or cracked lid can prevent proper sealing, even with a new gasket.
A clogged filter or damaged tube can cause priming issues that may be mistaken for a gasket leak.
Worn pump seals can also lead to loss of prime and should be checked if problems persist.
