Hydra part 432-604 is a 3/4" 100 mesh inlet strainer designed to filter debris and contaminants from the fluid before it enters the pump. This strainer helps protect internal pump components such as valves, pistons, and packings from wear and damage caused by particles. Regular replacement ensures optimal flow and extends the life of your Hydra sprayer.

The Hydra 432-604 Inlet Strainer (3/4" NPT, 100 mesh) is a critical filtration component designed to trap debris, rust, and other particles before they enter the pump. On compatible Hydra M and Hydra Pro Super sprayers, this strainer helps ensure clean fluid delivery, reducing the risk of clogged tips, valve sticking, and pump damage.
A clogged, torn, or missing strainer can lead to reduced flow, erratic pressure, and premature wear of pump packings and valves. Replacing the inlet strainer restores proper filtration and maintains pump efficiency.
| Filtration | 100 mesh screen captures particles as small as 149 microns |

Inlet flow issues are often tied to more than one component. When servicing the strainer, these parts are commonly inspected at the same time.
Kinks, cracks, or collapsed hose can restrict flow and mimic a clogged strainer.
Debris that passes a damaged strainer can lodge in inlet valves or piston packings.
Fine particles that escape the strainer often clog tip filters or the tip orifice.
