How Do I Know What Tip to Use on My Pressure Washer?

Match the tip to your machine first, then to the job. The tip's orifice size and PSI rating must fit the flow rate and pressure on your washer's label, and the spray angle should suit the surface. If you are unsure, start with the 40° white tip and only go narrower if the dirt will not budge.

Two checks decide the right tip

Choosing a tip comes down to two separate questions. The first is whether the tip fits your washer. The second is whether the spray angle suits what you are cleaning.

Fit is about numbers on your machine: pressure in PSI, flow in GPM and the type of connector on the wand. Angle is about the surface in front of you. Get the first one wrong and the tip can fail or perform poorly. Get the second one wrong and you can strip paint or gouge wood.

Step 1: Read your washer's label

Look for the rating label on the pump or frame, or check the manual. Write down the PSI and the GPM. You will need both.

Our best pressure washer nozzle page advises picking a nozzle rated at or above your washer's PSI. The listings there run from 3600 PSI to 5000 PSI. A tip rated below your machine can fail or wear out fast.

PSI rating: the tip's maximum should be equal to or higher than your washer's output.
Orifice size: this is the opening the water passes through, and it ties to flow in GPM. On our nozzle page, listings with a 4.0 orifice name 4.0 GPM, and one with a 2.5 orifice names 2.5 GPM.
Connector: many of the tips we compare use a 1/4 inch quick connect. Confirm that it fits your wand or gun before you order.
Water temperature: some listings state a limit, such as 180°F or 195°F. Keep your water below it.

Why orifice size matters

Orifice size is the part people skip, and it is the one that makes a tip feel wrong on the wrong machine. An opening that is too small for your washer's flow makes the pump work against the restriction. An opening that is too large lets pressure fall, so the spray feels weak.

Some makers leave orifice size out of the listing, and we note where that happens. If the size is missing, check the packaging or ask the seller before you buy. One turbo tip we compare says it suits washers from 1000 to 4000 PSI at 4.0 GPM and asks buyers to check their machine's pressure and flow first. That is good advice for any tip.

Step 2: Learn the color and angle chart

Most fixed tips follow the same color code. The angle tells you how wide the spray fan is. A smaller angle puts the same force on a smaller spot, so it hits harder. A wider angle spreads the force out and is gentler.

The sets we compare list this same order: red for 0°, yellow for 15°, green for 25°, white for 40° and black for 65° soap. Treat the uses below as general guidance, not rules.

Color	Angle	Common use	Care level
Red	0°	Spot work on bare concrete or metal, such as rust or stuck-on gum	Highest. Can cut and etch.
Yellow	15°	Stripping stubborn grime from hard surfaces	High
Green	25°	General cleaning of driveways, sidewalks and decks	Moderate
White	40°	Cars, siding, fences and delicate surfaces	Low
Black	65°	Applying soap at low pressure	Lowest

Step 3: Match the tip to the job

Begin with the widest tip that could plausibly work. Test it on a hidden patch. Move to a narrower tip only if the dirt stays put.

Here is a simple way to choose:

Rinsing a car, windows or painted siding: use 40°.
Sweeping leaves, mud or loose dirt off a deck or walk: use 25°.
Cleaning a concrete driveway or patio: start at 25°, then try 15° on oil or stains.
Applying cleaner: use the black soap tip, then rinse with a wider angle.
Spot-treating rust on metal: use 0° briefly, from a safe distance.

When a turbo tip makes sense

A rotating turbo tip spins a narrow jet in a cone. This gives you the scrubbing action of a narrow tip but covers a wider area. It suits stubborn grime on concrete, brick and garage floors.

The turbo tips on our nozzle page typically use a ceramic core with stainless steel, which is meant to resist wear under high pressure. One listing warns that zinc-coated tips can corrode over time. For example, the Xaxuqtu turbo tip has a 4.0 orifice, is rated for 4000 PSI and 180°F water, and weighs 0.24 lb. The SANLINGRIA turbo tip is rated for 5000 PSI and 195°F.

For big flat areas such as driveways, a pressure washer surface cleaner covers ground faster and leaves fewer streaks than any single tip. If you are still choosing a machine, our best power washer for home use and best gas pressure washer pages show how the specs compare.

Safety before you pull the trigger

A pressure washer can injure you as easily as it can clean. Treat it like a power tool.

Never point the wand at people or pets, and never put a hand or foot near the spray. A narrow tip can break skin and cause injuries that look minor but are serious. Wear safety glasses, closed-toe shoes and long pants. Gas models are loud, so wear hearing protection.

Do not change tips while the trigger can be pulled. Release the pressure, engage the trigger lock and, on a gas model, shut the engine off. Keep electric machines plugged into a GFCI outlet and keep connections out of standing water. Take extra care on ladders and roofs, because the wand kicks back when you squeeze the trigger.

Frequently asked questions

Can I use a 0° tip on my deck or siding?

It is best not to. The red tip concentrates all the force in a tiny spot and can gouge wood, strip paint and damage siding. Use 25° or 40° on those surfaces.

What happens if I use a tip rated below my washer's PSI?

The tip can crack, wear out fast or blow off the wand. Always check the tip's rated maximum against the label on your machine.

Do all pressure washer tips fit all wands?

No. Many tips use a 1/4 inch quick connect, but some wands use threaded fittings. Check your wand's connection type before buying.

Do I need a whole set or just one tip?

A set gives you several angles and often a soap tip, which helps if you clean many surfaces. If you mainly scrub tough concrete, one turbo tip may be enough.
