The Titan 0533513 Spring is an OEM compression or extension spring designed for PowrCoat 630 and AirCoat 423 spray systems. It provides the necessary return force or tension for components such as pressure regulators, valve stems, trigger safeties, or fluid control mechanisms.
Springs can weaken, take a set, or break over time due to repeated cycling, corrosion, or fatigue. A failed spring can cause erratic operation, loss of pressure control, or failure of a component to return to its proper position. Replacing with an OEM spring restores correct force and reliable function.
| Return force | Returns valves or actuators to their resting position |
|---|---|
| Pressure regulation | Provides counterforce in pressure control assemblies |
| Vibration damping | Reduces chatter in moving components |
| Broken or cracked spring | Visible break or coil separation |
|---|---|
| Loss of tension | Spring feels weak, does not return component fully |
| Corrosion or pitting | Rust or surface damage that can cause stress risers |
| Set or sag | Spring no longer maintains original free length |

When replacing a spring, inspect or replace these associated components to ensure proper assembly performance.
Worn valve stems can cause sticking and premature spring wear. Replace if pitted or scored.
Springs often work against seals; replace seals if they show wear or hardness.
Check for damaged or missing clips that retain the spring in its housing.
