Dig Pig Silencer Hydro Excavation Nozzle

The Dig Pig Silencer is a rebuildable turbo nozzle for hydro excavation and industrial cleaning. A 0° orifice turns in a 10° rotation inside a 303 stainless steel body, protected by a replaceable Hi-Vis yellow machined cover and an advanced coin filter system. The nozzle is rated for 4300 PSI and 205°F (96°C), and Dig Pig designs it for minimal vibration and low noise.

Select the orifice size in the dropdown. All seven sizes, 4.0 through 12.0, share the 1/2" MNPT inlet and the same price, and every component of the nozzle is sold separately for rebuilds.
