The 345-001 retainer spring is a critical tension component used in the SprayTech ED655 Plus sprayer. It applies consistent force to hold parts such as valve assemblies, filter covers, or access panels securely in place during operation, even under vibration and pressure fluctuations.
Over time, springs can weaken from metal fatigue, stretch beyond their working limit, or break due to corrosion or stress. A failed retainer spring can allow components to shift, leak, or detach, leading to poor performance or safety hazards. Replacing a worn or damaged spring with this OEM part restores proper retention and reliable operation.

When replacing a retainer spring, inspect these associated components that work with the spring.
The spring holds the valve in place; check the valve for wear or damage.
If the spring retains a filter, inspect the filter for clogs or deterioration.
Ensure the cover itself is not cracked or warped where the spring attaches.
