Hydra part 432-871 is a high pressure filter assembly designed to remove contaminants from the hydraulic fluid on compatible sprayers. This filter assembly protects critical components such as pumps, valves, and motors from wear and damage caused by particles in the hydraulic system. Regular maintenance and replacement of the filter assembly ensures clean fluid, extends component life, and maintains optimal hydraulic system performance.

The Hydra 432-871 High Pressure Filter Assembly is a genuine replacement component designed to remove contaminants from the hydraulic fluid on compatible Hydra M‑series and Pro Super sprayers. This filter assembly is installed in the high-pressure side of the hydraulic system, capturing particles that could cause wear, scoring, and premature failure of hydraulic pumps, valves, and motors.
Over time, filter elements become clogged with debris, restricting flow and reducing filtration efficiency. A restricted filter can lead to increased system pressure, overheating, cavitation, and reduced performance. Replacing the complete filter assembly—including the housing and element—ensures proper filtration, optimal system protection, and extended component life. The 432-871 assembly includes all necessary components for a complete replacement.
| Contaminant removal | Traps particles in the high-pressure hydraulic circuit |
|---|---|
| Component protection | Prevents wear and damage to pumps, valves, and motors |
| Fluid cleanliness | Maintains clean oil for optimal system performance |
| System efficiency | Clean fluid ensures proper lubrication and heat transfer |
| Scheduled maintenance | Replace at intervals specified in your owner's manual |
|---|---|
| Restriction indicator | Filter gauge or indicator shows clogged condition |
| Performance loss | Sluggish operation, slow cycle times, or pressure drop |
| Overheating | System runs hotter than normal due to restricted flow |
| After contamination event | If pump failure occurred or contaminated fluid was added |
| Housing damage | Cracks, leaks, or damaged threads on the filter housing |
Hydra part 432-871 is compatible with the following Hydra sprayer models. Always confirm fitment using the correct parts diagram for your exact model and serial number.
