Part number 34357 is a genuine compression spring used in Elite 5500 and PowrLiner 4500/5500 airless sprayers. This precision-wound spring provides controlled force to maintain pressure on valves, seals, or other components within the pump or drive system. It ensures proper seating of valve components, maintains tension on moving parts, and absorbs shock loads during operation. A worn, fatigued, or broken compression spring can cause valve leakage, pressure loss, erratic operation, or system failure. This genuine replacement restores proper spring force and reliable operation.

The 34357 Compression Spring is a genuine OEM component designed for Elite 5500 and PowrLiner 4500/5500 airless sprayers. This precision-engineered spring is manufactured to exact specifications for wire diameter, coil count, free length, and spring rate, ensuring consistent force application in critical sprayer systems.
Compression springs serve multiple functions in airless sprayers. They provide the necessary force to keep valve components properly seated, maintain tension on seals and packings, absorb shock and vibration from pump operation, and return moving parts to their correct positions. In valve assemblies, the spring ensures the valve closes completely and quickly, preventing backflow and maintaining pressure. In other applications, springs may provide tension on drive components or maintain contact between moving parts.
Over time, compression springs can fatigue, lose tension, or break due to millions of compression cycles. A worn or broken spring can cause valves to leak, pressure to drop, components to rattle or vibrate excessively, and overall sprayer performance to degrade. Replacing a fatigued spring with this genuine part restores proper force, ensures reliable component operation, and extends the life of the sprayer.
| Valve actuation | Provides force to close valves and maintain seal |
|---|---|
| Shock absorption | Absorbs impact and reduces stress on components |
| Position maintenance | Holds components in correct position during operation |
| Tension control | Maintains proper tension on seals and moving parts |
| Loss of tension | Spring feels weak or does not provide adequate force |
|---|---|
| Visible fatigue / cracking | Spring shows cracks, corrosion, or deformation |
| Broken spring | Spring is fractured or broken into pieces |
| During valve service | Always replace spring when rebuilding valves |

When replacing a compression spring, it's good practice to inspect these related components.
Inspect valve seats, balls, and guides for wear. Replace as needed when servicing springs.
Check adjacent seals for wear or damage. Replace to prevent leaks.
Inspect surfaces where the spring seats for wear or damage.
