General Pump Red High-Pressure Industrial Turbo Nozzle - 5100 PSI, 4.0 GPM

When extreme cleaning demands push past standard limits, the General Pump YR51K40 Red Industrial Turbo Nozzle steps up. Engineered for industrial pressure washers operating at 4,000+ PSI and 4 GPM, this nozzle spins a zero-degree jet stream at high velocity into a wide, hard-hitting circular cleaning path — cutting through severe scale, caked grease, and epoxy coatings in a fraction of the time required by standard spray setups.

Built for Severe Commercial Environments

The YR51 Series features an ultra-premium low-friction ceramic rotating core that keeps internal temperatures in check even during long continuous-use shifts. The heavy-duty red rubber outer casing protects structural components from cracking or rupturing due to accidental drops on rebar, gravel beds, or scaffolding — giving you maximum field reliability.
