The Titan 2418851 20" Gun Extension is a genuine OEM replacement extension that installs between the spray gun and the tip guard, adding 20 inches of reach. It replaces the previous part number Titan 651-072 and is sold as an individually packaged unit. This extension is ideal for high ceilings, exterior walls, stadium seating, and other applications where extended reach is essential.
A damaged, bent, or missing extension can make precise spraying difficult and increase operator fatigue. Replacing with the correct OEM extension restores original reach, balance, and thread compatibility.
| Extended reach | Adds 20 inches between gun and tip for high or distant surfaces |
|---|---|
| Improved ergonomics | Reduces need for ladders or scaffolding when spraying high areas |
| Thread compatibility | Standard thread pattern fits Titan airless guns and tips |
| Bent or deformed extension | Visibly out of straight, affects spray accuracy |
|---|---|
| Damaged threads | Cross‑threaded or stripped threads prevent secure attachment |
| Leaking at connection | Paint seeps between gun and extension or extension and tip |
| Corrosion or pitting | Rust inside or outside can contaminate paint or weaken the metal |

When replacing a gun extension, these related components are often inspected or replaced at the same time.
