Titan 13364 Wave Spring

Titan 13364 Wave Spring

Sourced From:
Titan Tools Inc.

 

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.

Service Note: When replacing the wave spring, inspect the adjacent seals, seats, and retainers for wear. Always consult your pump parts diagram to confirm correct orientation and stack‑up order.

What it does and when to replace it

Function of the wave spring
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
When replacement is recommended
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

Compatibility

SprayTech wave spring 13364 is used in the pump assemblies of the following models. Always verify fitment with your unit’s parts diagram.

SprayTech Model Component

Related parts commonly serviced together

When replacing the wave spring, inspect these associated components for wear or damage.

Seal / packing kit

Worn seals often accompany a collapsed wave spring. Replace as a set.

Check valve assembly

Ball, seat, or retainer wear can mimic wave spring failure symptoms.

Piston / rod assembly

Scratches or corrosion can damage seals and affect spring preload.

Frequently Asked Questions

The wave spring provides a constant preload force on seals, check valves, or packing. This ensures proper sealing, compensates for part tolerances and thermal expansion, and helps maintain steady fluid pressure during spraying.

Common signs include pressure surging or loss, reduced spray output, fluid leakage from the pump area, or a visibly flattened/cracked spring when inspected. If the sprayer runs but fails to build consistent pressure, the wave spring is a likely culprit.

It is compatible with SprayTech EP2300, EP2400, EP2300 SE, EP2510, and 2413371. Always cross-reference your pump parts diagram to confirm fitment.

While you can replace just the spring, it's recommended to inspect the seals, check valve, and piston rod for wear. Many professionals replace the seal packing kit together with the wave spring to ensure full pump restoration and avoid repeat failures.
