The 9920204 Washer is a genuine OEM fastener component designed for Elite 5500 and PowrLiner 4500/5500 airless sprayers. This precision-manufactured washer is used in various locations throughout the sprayer, including under bolt heads, nut mating surfaces, and in conjunction with seals to provide load distribution and sealing functions.
Washers play several critical roles in mechanical assemblies. They distribute the clamping load of a fastener over a wider area, preventing damage to softer materials such as plastic housings or painted surfaces. They can act as spacers to achieve proper component alignment. In some applications, they provide a sealing function when used with O-rings or as part of a fluid connection. They also help prevent galling between dissimilar metals and can compensate for slight variations in component dimensions.
This genuine washer is manufactured to exact factory specifications for material composition, thickness, inside and outside diameter, and hardness. Using the correct washer ensures proper fastener tension, prevents loosening from vibration, and maintains the integrity of assembled components. A missing, deformed, or corroded washer can lead to insufficient clamping force, fastener loosening, fluid leaks, or damage to surrounding parts.

When replacing washers, it's good practice to inspect these related components.
Inspect mating fasteners for thread damage, corrosion, or wear. Replace if necessary.
Check nuts for thread damage or distortion. Replace with new fasteners as needed.
Inspect surfaces where washer seats for damage, burrs, or debris that could affect proper seating.
