Keep your SE7ENTEEN nozzle in service without replacing the complete assembly. The Dig Pig SE7ENTEEN Nozzle Refresh Kit provides the primary internal wear and service components needed to refresh a SE7ENTEEN hydro-excavation nozzle when performance starts to drop or internal components are worn. 

The kit includes the full rotor system, seat, required O-rings, and advanced coin filter. Dig Pig offers the Refresh Kit in 4.0, 6.0, 8.0, 9.0, 10.0, and 12.0 orifice sizes, so you'll want to match the kit to your existing SE7ENTEEN nozzle size.
