Titan part 800-935 is a line surge protector (also known as a pressure surge damper or pulsation dampener) used on compatible airless sprayers and stripers. This device absorbs pressure spikes and reduces pulsation from the pump, resulting in a smoother spray pattern and reduced wear on hoses, gun, and tip. A failed or missing surge protector can cause excessive tip wear, erratic spray, and increased component fatigue. Replacing it restores consistent fluid delivery and extends equipment life.

The Titan 800-935 Line Surge Protector is a hydraulic pulsation dampener installed between the pump outlet and the hose. It uses a compressible gas or spring‑loaded diaphragm to absorb pressure spikes created by the reciprocating piston pump, smoothing the flow to the spray gun.
Over time, the internal diaphragm can rupture or lose precharge, rendering the surge protector ineffective. Symptoms include a "chattering" spray pattern, rapid tip wear, hose vibration, and increased pressure fluctuation on the gauge. Replacing the unit restores a steady stream and protects downstream components.
| Dampens pulsation | Smoothes pressure spikes from pump |
|---|---|
| Reduces tip wear | Eliminates hammering that erodes spray tips |
| Protects hoses | Absorbs shock loads, extending hose life |
| Improves finish | Delivers consistent flow for even coating |
| Rough / chattering spray | Spray pattern pulses visibly at the tip |
|---|---|
| Excessive tip wear | Tips clog or erode faster than normal |
| Hose vibration | Hose jumps or shakes during operation |
| Pressure gauge fluctuation | Needle swings widely instead of steady |

When replacing the surge protector, inspect these associated components.
A worn tip can mimic surge protector failure; inspect and replace as needed.
Worn inlet/outlet valves cause severe pulsation that may overload the surge protector.
Inspect for kinks or internal damage that could create pressure spikes.
