The Titan 0508315 Inlet Valve Housing O‑Ring is a genuine OEM replacement seal designed for the inlet valve housing on SprayTech Airless EP2205 and EP2105 sprayers. It creates a leak‑tight seal between the inlet valve housing and the pump body, preventing paint from leaking externally and stopping air from being drawn into the fluid stream.
A worn, flattened, or damaged inlet valve housing O‑ring can cause fluid leaks from the inlet area, difficulty priming, loss of prime during operation, or erratic spray performance. Replacing this O‑ring restores proper sealing and reliable sprayer function.
| Prevents external leaks | Seals the joint between inlet housing and pump body |
|---|---|
| Blocks air ingestion | Prevents air from being sucked into the fluid stream |
| Maintains prime | Helps the sprayer retain prime during operation and between cycles |
| Fluid leak at inlet housing | Paint weeping from between housing and pump body |
|---|---|
| Loss of prime / hard to prime | Sprayer loses prime easily or requires repeated priming |
| Air bubbles in fluid stream | Intermittent spitting or foamy paint from air ingestion |
| Flattened or cracked O‑ring | Visible damage during service; O‑ring has lost elasticity |
