Part number 0529920 is a complete FlexSpray Air Tube and Valve Seal Kit. This service kit contains all the wearable seals, O-rings, gaskets, and internal components required to rebuild the air distribution system of the FlexSpray and FlexSpray HH spray guns. It includes components for the air valve assembly, trigger mechanism, and internal air passages.
Over time, the internal seals in a spray gun can become worn, dried out, or damaged due to exposure to solvents, cleaning agents, and normal mechanical cycling. A gun with worn air seals will exhibit symptoms such as air leaking from the trigger area or handle, difficulty triggering, inconsistent spray pattern, or the gun continuing to spray air after the trigger is released.
Rebuilding the air system with this kit restores the gun's pneumatic integrity, ensuring that compressed air is delivered precisely when and where it is needed for proper atomization and pattern control. This is a cost-effective alternative to replacing the entire gun assembly.

When rebuilding the air system, these related components are often inspected and serviced at the same time for complete gun restoration.
A fresh air filter ensures clean air enters the rebuilt valve system. Part number 0529917 is the recommended replacement.
The O-ring sealing the air hose to the gun handle should be replaced to prevent leaks at this connection point.
While servicing the air side, consider inspecting the fluid needle packing which may also show signs of wear.
