Rotary Pressure Washer Nozzle – 4.5 Orifice

Part Number: 85.210.145
Category: Pressure Washer Spray Nozzles
Type: Rotary Turbo / Rotating Nozzle

The Rotary Pressure Washer Nozzle – 4.5 Orifice is engineered for maximum cleaning power on the toughest hard surfaces using high-flow pressure washer systems. By combining the concentrated force of a 0° jet with a high-speed rotating spray pattern, this nozzle delivers aggressive scrubbing action while covering more surface area than standard fixed nozzles.

Designed for durability and efficiency, it’s an excellent choice for contractors and homeowners tackling heavy buildup on concrete, stone, and masonry.
