The 89595 Washer is a standard flat washer used in PowrBeast Airless Sprayers and Hydrax 4540-7230 equipment. It serves as a critical component in fastener assemblies, providing a smooth bearing surface under bolt heads and nuts to distribute clamping load and prevent surface damage.
Flat washers distribute the clamping load over a wider area, preventing damage to mating surfaces and reducing the risk of fastener loosening due to embedment. They also act as spacers and can compensate for slightly oversized holes. Replacing worn, corroded, or missing washers ensures proper joint integrity and extends equipment life.

|---|---|
| Surface protection | Prevents fastener head from marring or embedding into mating surface |
| Spacing / alignment | Helps achieve proper positioning of assembled components |
| Corrosion | Rust or chemical damage has weakened the washer |
|---|---|
| Deformation | Washer is bent, warped, or no longer flat |
| Missing | Washer absent during disassembly; always replace |
