Choosing the correct pressure washer nozzle is essential for achieving the best cleaning performance. Pressure washer nozzles are available in various sizes and spray patterns, each meticulously designed for specific cleaning tasks. For instance, a 0-degree nozzle is perfect for targeting tough stains with a concentrated, high-impact pencil jet. Selecting an inappropriate size nozzle can result in potential equipment damage, making it imperative to adhere to the manufacturer's guidelines or seek professional advice to ascertain the right choice for your pressure washer based on your specific cleaning requirements. All nozzles are available with a 1/4" and 1/8" inlet thread.
