Pressure washer nozzles: types and materials

Varieties pressure washer nozzles exist, each designed for a distinct spray pattern and suited for different cleaning jobs. Let's explore!

Different types of pressure washer nozzles

0 degree nozzle (red)

Spray pattern: produces a very concentrated, powerful stream of water.

Ideal use case: suitable for removing stubborn stains on metal, concrete and bricks.

15 degree nozzle (yellow)

Spray pattern: forms a narrow, high-pressure fan-shaped stream of water.

Ideal Use Case: Perfect for prepping for painting or sealing, and effective at removing stubborn dirt and paint from hard surfaces.

25 degree nozzle (Green)

Spray Pattern: Disperses water into a wider fan, slightly reducing water pressure.

Ideal Use Case: For general cleaning tasks, like cleaning decks, patios and driveways.

40 degree nozzle (White)

Spray Pattern: Produces a wide spray angle, providing the gentlest pressure.

Ideal Use Case: For gentle washing of large areas and delicate surfaces such as windows and cars.

65 degree soap nozzle (Black)

Spray Pattern: Provides a very wide, low-pressure spray for applying soap.

Ideal Use Case: Apply cleaning solution to large areas, then switch to the high pressure nozzle for rinsing.

turbo nozzle

Spray Pattern: Rotates the spray pattern in a circular motion.

Ideal Use Case: Quickly cleans dirt from large, flat surfaces.

sewer jetter nozzle

Spray Pattern: Directs water backward, pushing it through pipes and drains to clear clogs.

Ideal Use Case: Cleans and unclogs drains and sewers.

Nozzle Materials

Pressure washer nozzles are generally made from following materials:

Stainless steel: Known for durability and corrosion resistance, perfect for heavy duty use.

Brass: Recognized for strength and resistance to corrosion,often used in general purpose nozzles.

Plastic: Lightweight and cost effective, but less durable, making it suitable for lighter tasks.

Factors that influence nozzle selection

Selecting ideal nozzle for your pressure washer involves various factors to guarantee it fits surface to clean, cleaning job and compatibility with pressure washer. Let's explore each of these factors.

Surface Type

Different surfaces require different levels of water pressure. Choosing the right nozzle can help prevent damage to delicate surfaces while ensuring effective removal of stubborn stains.

Hard Surfaces: Concrete and metal require high pressure nozzles (0 degree and 15 degree).

Medium Surfaces: Wood and vinyl are suitable for medium pressure (25 degree nozzles).

Delicate Surfaces: Windows and vehicles require low-pressure, wide spray (40 degree nozzles).

Cleaning Task

The choice of nozzle also varies based on cleaning task you need to accomplish. Whether tackling everyday grime or persistent stains, selecting appropriate nozzle can enhance your efficiency.

Stubborn stains: Use a 0 degree or 15 degree nozzle.

General cleaning: A 25 degree nozzle is suitable for a variety of surfaces.

Delicate cleaning: A 40 degree nozzle is used for delicate surfaces.

Soap application: Apply cleaning solution with a 65 degree soap nozzle.

Pressure washer compatibility

Ensure nozzle is compatible with PSI and GPM ratings of pressure washer. Below is a straightforward chart to assist you in selecting a nozzle size that fits your pressure washer's specifications.

Choosing a nozzle with overly large orifice will lower operating pressure, while opting for one with excessively small orifice can limit water flow and potentially overload machine.

Taking these factors into account helps to choose right pressure washer nozzle wisely.

How to change a pressure washer nozzle

Preparation

Turn off pressure washer and disconnect all power sources. If it's gas powered, ensure engine is off. Squeeze spray bar trigger to release built-up pressure. This is crucial to prevent accidental spraying when changing nozzles.

Remove the old nozzle

Locate nozzle tip on the spray bar. If your pressure washer has a quick connect system, pull back collar to release nozzle.

Install the new nozzle

Align the new nozzle with the quick-connect collar on the spray bar and push in until you hear a click.

Test the new nozzle

Reconnect and start the washer to test the nozzle. If necessary, make adjustments to ensure you get an even and task appropriate water flow.

By following these steps, you can easily change nozzle on high pressure washer.

Conclusion

Choosing correct pressure washer nozzle ensures efficient and safe cleaning. Understand each nozzle's purpose and match it with pressure washer's PSI and GPM for optimal results. BISON suggests experimenting with various nozzles to discover best fit for more effective and enjoyable cleaning tasks.
