Titan 13364 Wave Spring
SprayTech part 13364 is a wave spring used in the fluid section or pressure control assembly of compatible EP‑series sprayers. The wave spring maintains consistent axial load on seals, valves, or pistons, helping compensate for minor wear and thermal movement. Replacing a worn or collapsed wave spring restores proper sealing pressure and reliable pump operation.

Wave Spring for SprayTech EP-Series Airless Sprayers
The SprayTech 13364 Wave Spring is a precision-engineered, wave‑shaped compression spring designed to deliver consistent axial force within the fluid pump assembly. It is commonly used to preload check valves, piston seals, or packing cartridges – ensuring proper sealing and steady fluid delivery.
Over time, wave springs can take a permanent set, lose tension, or crack due to cyclic fatigue. Symptoms include pressure fluctuation, reduced output, erratic spray pattern, or leakage past the pump section. Replacing with genuine SprayTech 13364 restores factory pump performance and reliability.
What it does and when to replace it
| Maintains preload | Applies constant axial force to seals or check valves |
|---|---|
| Compensates tolerances | Absorbs thermal expansion and minor part wear |
| Prevents leakage | Keeps sealing faces in contact under varying pressures |
| Pressure loss / surging | Sprayer pressure fluctuates or fails to hold steady |
|---|---|
| Visible damage | Cracked, flattened, or deformed wave spring |
| Leakage from pump | Fluid bypass or dripping from the packing area |
| Reduced output | Sprayer runs but delivers lower flow than normal |
