The Titan 0290443A Filter Cap Assembly with Spring Support is a genuine OEM replacement component for the fluid filter housing on PowrBeast, PowrTwin, and PowrLiner airless sprayers and line stripers. It includes the filter cap, spring support (spring and retainer), and associated sealing elements, all pre‑assembled for a quick, reliable installation.
The filter cap seals the filter chamber, while the spring support maintains constant pressure against the filter element, ensuring debris is captured without bypass. A cracked cap, weak or missing spring, or damaged threads can cause leaks, poor filtration, or loss of prime. Replacing the complete assembly restores proper filter function and system integrity.
| Sealed filtration | Cap creates a leak‑tight closure for the filter chamber |
|---|---|
| Spring tension | Spring support keeps filter element seated against the housing |
| Debris bypass prevention | Maintains proper flow path so all fluid passes through the filter |
| Cracked or broken cap | Visible damage causing fluid leaks or inability to tighten |
|---|---|
| Weak or missing spring | Spring does not push filter element firmly; filter may rattle or bypass |
| Cross‑threaded cap | Damaged threads prevent proper sealing and tension |
| Leakage from cap area | Paint or solvent seeps past the cap despite a new gasket |

When replacing the filter cap assembly, these related components are often inspected or replaced at the same time.
Replace the internal filter element (often a mesh or paper cartridge) at the same time to ensure optimal filtration.
The cap assembly may include a gasket; if not, replace the housing seal separately to prevent leaks.
Inspect the housing for cracks, debris, or damaged threads that could affect the new cap assembly.
