Get the job done with the Karcher Turbo Nozzle. Certain hard surfaces (think driveways, asphalt, concrete, brick and stone) may require more intense cleaning. While you could use a 0-degree (pencil jet) spray nozzle, that method can be very time consuming. The Karcher Turbo High Pressure Nozzle takes a 0-degree nozzle and rotates it at high speed, giving you the effective cleaning power of a pencil jet but with a wider area of cleaning. This greatly speeds up the task of deep cleaning hard surfaces. This pressure washer nozzle fits Karcher and most other brands rated up to 4000 PSI. Quick Connect. Not for use on delicate surfaces.
