Pressure Washer Orifice Size Calculator

FAQs

What is the orifice on a pressure washer tip? The orifice on a pressure washer tip is the small opening at the end of the nozzle that determines the spray pattern and pressure. It plays a crucial role in regulating the flow of water and creating the desired pressure.

How do I know what size orifice for my pressure washer? The size of the orifice you need depends on your pressure washer’s specifications and the desired pressure. Manufacturers often provide guidelines in the user manual or online resources. Orifice sizes are typically measured in thousandths of an inch (e.g., 2.5 orifice). A smaller orifice size will result in higher pressure and a narrower spray pattern, while a larger orifice will lower the pressure and provide a wider spray.

How do I choose an orifice size? Choose an orifice size based on the pressure rating of your pressure washer and the task you’re performing. If you’re unsure, start with the manufacturer’s recommended orifice size and adjust as needed. Smaller orifices provide more pressure and are suitable for tougher cleaning tasks, while larger orifices are better for delicate surfaces.

What is the best orifice size for a foam cannon? A common orifice size for a foam cannon is around 1.1 to 1.5 mm. This size provides a good balance between producing a thick foam and maintaining adequate pressure for effective cleaning.

Does an orifice change pressure? Yes, the orifice size directly affects the pressure. A smaller orifice will increase pressure, while a larger orifice will decrease it.

How does orifice size affect pressure? Smaller orifices restrict water flow, which leads to higher pressure. Conversely, larger orifices allow more water to flow, resulting in lower pressure.

Does a Turbo nozzle increase PSI? A turbo nozzle doesn’t technically increase the pressure of the pressure washer, but it concentrates the water flow to produce a rotating, high-intensity spray that can effectively clean tough surfaces. It provides better cleaning power compared to a standard nozzle at the same pressure.

What color tip is the strongest for a pressure washer? In the common color-coding system, white or yellow tips are typically the strongest, with a narrow spray angle that provides higher pressure for intense cleaning. However, the exact color-coding can vary between manufacturers.

Are turbo nozzles worth it for a pressure washer? Yes, turbo nozzles are often worth it as they provide increased cleaning power by combining high pressure with a rotating spray pattern. They’re particularly useful for removing stubborn dirt, grime, and stains.

How can I make my pressure washer stronger? To make your pressure washer stronger, you can:

• Use a smaller orifice for increased pressure (be cautious not to exceed your pressure washer’s limits).
• Use a turbo nozzle for more effective cleaning.
• Check and clean filters and nozzles for optimal performance.
• Ensure your water supply is providing sufficient flow.

What is the difference between 80-degree and 110-degree spray nozzles? 80-degree and 110-degree spray nozzles provide wide spray patterns for covering larger areas with minimal pressure. The difference lies in the angle of coverage; a 110-degree nozzle will have a wider spray angle compared to an 80-degree nozzle.

What is a 40-degree nozzle used for? A 40-degree nozzle provides a wider spray pattern, making it suitable for more general cleaning tasks, such as washing cars, windows, and siding. It’s gentler on surfaces compared to lower-degree nozzles.

Does orifice size affect flow rate? Yes, orifice size directly affects flow rate. A smaller orifice restricts flow, resulting in a lower flow rate, while a larger orifice allows more water to flow, increasing the flow rate.

What size is a 42 orifice? A 42 orifice is typically measured in 1/1000ths of an inch, so it would be 0.042 inches in diameter.

What is the difference between a standard orifice and a small orifice? A standard orifice refers to the default nozzle size that comes with your pressure washer, providing a balance between pressure and flow. A small orifice would typically refer to a narrower orifice size, which increases pressure but reduces flow, suitable for tougher cleaning tasks.
