Hydra part 813-009 is a pipe cross designed for use on Hydra M 2000, Hydra M 4000, and Hydra Pro Super sprayers. This fitting connects four fluid or air passages at right angles, allowing for distribution or collection of material within the sprayer's hydraulic or fluid circuit. Replacing a cracked, corroded, or worn pipe cross restores proper flow paths, prevents leaks, and ensures reliable system operation.

The Hydra 813-009 Pipe Cross is a genuine OEM fitting used in the fluid or hydraulic circuits of Hydra M 2000, Hydra M 4000, and Hydra Pro Super sprayers. This four‑way fitting allows connection of pipes or hoses at perpendicular angles, enabling distribution of material to multiple outlets or collection from multiple inlets. Precision‑machined to maintain proper flow dynamics, it is critical for balanced system performance.
Over time, pipe crosses can become cracked due to vibration or overtightening, corroded from exposure to harsh chemicals, or worn from internal erosion. A damaged fitting can cause fluid leaks, pressure imbalance, and reduced spray efficiency. Replacing with the correct 813‑009 pipe cross restores proper flow paths, eliminates leaks, and ensures reliable, consistent operation.
| Four‑way connection | Joins four fluid passages at right angles |
|---|---|
| Flow distribution | Distributes material to multiple components (e.g., spray guns, valves) |
| System integrity | Maintains leak‑free operation under pressure |
| Cracked / broken | Visible cracks in the body, especially near threads |
|---|---|
| Corroded / pitted | Surface corrosion that weakens the fitting or contaminates fluid |
| Leaking | Fluid seeps from the fitting despite tightened connections |
| Stripped threads | Unable to achieve a secure seal with pipe fittings |
Hydra part 813-009 is compatible with the following models. Always confirm fitment using the correct parts diagram for your exact model and serial number.
| Model | Component |
|---|---|
| Hydra M 2000 | Pipe Cross |
| Hydra M 4000 | Pipe Cross |
| Hydra Pro Super | Pipe Cross |
When replacing a pipe cross, inspect these associated components for wear or damage.
Check the threaded fittings that connect to the cross for damage or corrosion.
Use fresh thread sealant or PTFE tape when installing the new cross to ensure leak‑free connections.
Inspect hoses connected to the cross for cracks or abrasion that may have contributed to fitting stress.
