Part 434-673 is a dual outlet used to split fluid flow for simultaneous operation of two spray guns or tips on Hydra M and Hydra Pro Super sprayers. It provides balanced pressure distribution and allows for increased productivity in large-scale applications. Replacing a worn, leaking, or damaged dual outlet restores proper flow division and consistent spray performance.

The 434-673 Dual Outlet is a fluid manifold that splits the output from the pump into two separate flow paths, enabling simultaneous operation of two spray guns or tips on Hydra M and Hydra Pro Super sprayers. This increases productivity for large-area applications and allows two operators to work from a single machine. Constructed from high-strength materials with precision-machined passages, it maintains balanced pressure to both outlets.
Over time, dual outlets can suffer from internal wear, seal degradation, or physical damage from impact or overtightening. A worn or damaged dual outlet may cause pressure drops between guns, uneven spray patterns, or external leaks. Replacing it restores balanced flow and ensures consistent performance for multi-gun operations.
| Flow splitting | Divides pump output for two guns or tips |
|---|---|
| Pressure balance | Maintains consistent pressure to both outlets |
| Increased productivity | Enables simultaneous operation by two users |
| Uneven flow | One outlet delivers less pressure/volume |
|---|---|
| Leaks | Fluid seepage at outlets or connections |
| Thread damage | Stripped or cross-threaded outlet ports |
| Internal wear | Pressure drop when both guns are used |
Part 434-673 is compatible with the following Hydra sprayer models. Always confirm fitment using the correct parts diagram for your exact model and revision.
| Model / Series | Component |
|---|---|
| Hydra M Series | Dual Outlet |
| Hydra Pro Super | Dual Outlet |
When replacing the dual outlet, inspect these associated components for wear or damage.
Worn guns can affect backpressure and flow balance.
Check for kinks, abrasion, or loose fittings.
Ensure smooth rotation and leak-free seals.
