The UnitedBuilt BC2178 duckbill flusher spray nozzle delivers a flushing pattern for compatible front, side, or rear water truck installations. Its 3/32-inch × 7-inch slot and 3-inch grooved inlet provide the outlet and connection dimensions needed to match an existing flusher nozzle or plan a new installation.
An original UnitedBuilt design, the BC2178 is sand cast in the USA from A356 aluminum for corrosion resistance in water spray service. Select it for applications requiring this flusher configuration, and check the mounting position and water supply before installation.
Flushing from the front, side, or rear
The duckbill outlet distributes water in a flushing pattern. Install the nozzle in the appropriate position for the area you need to flush, allowing clearance for the nozzle and its discharge. Actual coverage depends on flow, pressure, orientation, and mounting height; the 7-inch slot width is a physical dimension, not a ground-coverage rating.

Before ordering
Compare the slot opening as well as the inlet size when replacing a nozzle. A shared 3-inch connection or 7-inch slot width does not establish that two nozzles have the same discharge configuration.
| Check |
What to confirm |
| Connection |
Match the 3-inch grooved inlet to the plumbing, coupling, and gasket. |
| Outlet dimensions |
Confirm the required 3/32-inch slot opening and 7-inch width. |
| Installation location |
Check front, side, or rear mounting clearance and the intended discharge direction. |
| Water supply |
Confirm available flow and pressure suit the flushing system; contact UnitedBuilt for application assistance. |
