Everything You Need To Know About Airless Paint Sprayer Tips

Airless sprayers are extremely versatile tools that offer fast, efficient paint coverage. They can be fitted with a plethora of airless paint sprayer tips, also known as nozzles, which dispense a wide range of materials.

Spray tips for airless sprayers allow you to control the amount of paint atomized, and the fan pattern width. By choosing the correct tip for the job you’re completing and the coating you’re using, you can cut down on paint waste and better control the spray.

By gaining a solid understanding of how to choose airless paint tips you can get a flawless, professional finish every time. But, how do you know which airless paint sprayer nozzle is right for a large surface, and which is best for detailed, precision work?

Here, I delve into the details of how to identify the different spray tip sizes, explain what they mean, and let you know which coatings they suit best.

Airless Paint Sprayer Tip Sizes

There are three numbers stamped on airless sprayer nozzles which denote the width of the fan pattern and the aperture of the tip that the paint atomizes through. Let’s look at which numbers represent which, and how to interpret them.

The first number denotes the fan pattern width the airless tip can achieve when held about 12 inches away from your chosen surface. However, it’s not as straightforward as that — you have to multiply this first digit by two to get the tip’s fan width.
For example:

  • A 315 tip produces a six-inch fan pattern (3 x 2)
  • A 415 nozzle offers an eight-inch fan pattern (4 x 2)
  • A 513 spray tip gives a ten-inch fan pattern (5 x 2)
  • … and so on.

If you prefer to work in metric, then you can multiply this first number by five to get the fan width. A 515 spray tip will give a fan pattern width of 25 centimeters, for instance.

It’s worth noting that fan widths aren’t written in stone and can vary two inches either way depending on material choice and your airless sprayer’s pressure output.

This first number also indicates the spray fan’s angle when you’re holding the gun perpendicular. This is pretty simple to work out — just add a zero to the number, so if it’s 1, the angle is 10 degrees, 2 is 20 degrees, 5 is 50 degrees, and so on.

Tip Aperture

The opening in the spray tip is where your paint is atomized into a fine mist and the magic happens. Along with the air pressure, tip aperture controls the amount of material dispensed; the larger the orifice, the more material can pass through.

Aperture is denoted by the last two numbers on the spray tip and is measured in thousandths of an inch.

For example:

  • 315 airless sprayer tips measure 15 thousandths (0.015).
  • 517 airless spray gun tips measure 17 thousandths (0.017).
  • 535 airless paint sprayer tips measure 35 thousandths (0.035).

This is by no means an exhaustive list of airless sprayer tip sizes, but it should give you an idea of the extensive range on offer.

Now you know how to work out what the numbers mean, let’s take a look at how tip sizes relate to the viscosity of coatings.

Airless Sprayer Tip Sizes and Material Viscosity

Another factor that comes into play when picking the correct airless paint sprayer tip sizes is the thickness or viscosity of the material you’re spraying.

Because there are so many airless tip sizes available, you have a world of choice when it comes to paint thickness. Whether your coating is very thin or heavy and viscous, there’s a nozzle that can deliver.

The range of materials you can spray include:

THINWater sealers, varnish, clear coat lacquer, primer, stain
MEDIUMOil-based enamel, latex, primer oils, clear acrylics, primer, filler
HEAVYSmooth elastomeric, heavy latex, polymers, anti-corrosive paint, heavy fillers
VERY HEAVYElastomerics, block fillers, fire retardants, anti-corrosive paint

It’s always a good idea to check the paint manufacturer’s recommendations when choosing your spray tip. Most offer a helpful accurate guide.

Below is a quick reference chart detailing different materials and the range of spray tip sizes that can dispense these. This doesn’t incorporate every type of coating out there, but gives you a good starting guide.

Airless Paint Sprayer Tips and Tricks

Choosing the right spray tip for the job can make the difference between resounding success or abject failure. It influences the quality of the finish and the speed of application — and ultimately the cost-effectiveness of your project.

There are three simple factors to consider when choosing the best spray tip for a given job:

1. Choose Your Material and Corresponding Tip Size

Once you find the coating you want to apply, check the manufacturer’s recommended tip size, which is denoted by the last two numbers. Keep in mind, the thinner the coating the smaller the tip’s aperture, and vice versa. If a material is viscous, it will need a larger aperture.

Be mindful of the fact that there could be more than one suitable spray tip size, such as a 215, 315, or 415. The difference is the width of the fan pattern for each, and the thickness of the coat they apply.

2. Select Your Fan Pattern

After identifying the aperture needed to spray your chosen medium, decide how wide a fan pattern you want. That’s the first number on the tip multiplied by two. For example, a “5” series tip offering a 10-inch fan pattern won’t be good for trims but a “12” series with a 24-inch spray pattern would be great for large areas on new builds.

3. Make Sure Your Airless Sprayer is Compatible

Finally, check that your brand of airless sprayer supports your material and tip choice. While these machines are versatile, some have their limits.

Frequently Asked Questions

Q: How Often Should I Change My Spray Tip?

A new airless spray tip is good for about 40 to 50 gallons on average. Abrasive particles in paint can distort the shape of the aperture over time, changing it from a long thin oval, to a short round opening. This affects the amount of paint passing through, and the fan pattern.

You can tell if your tip is wearing out if you notice:

  • Your spray pattern develops bands of light and dark areas.
  • You get a smaller fan width than you’re used to seeing.
  • Your paint runs out faster than you would normally expect.
Q: What Does an Airless Spray Tip Do?

The spray tip is the part of your airless sprayer where the magic happens — high pressure from the gun’s pump forces the material through the small hole in the spray tip. The result is a fine, atomized paint that can be applied quicker, and with fewer imperfections than using a brush and roller.

Q: How Often Should I Clean My Airless Spray Tip?

Your spray tip should be cleaned after every use and before storing your sprayer. If you fail to clean your tips and gun properly, paint will dry and build up on the nozzle, rendering it useless.

Q: Are Spray Tips Interchangeable Between Brands?

To get the best from a spray tip, I would always recommend using the correct manufacturer’s tip for your brand. That being said, there are some very good generic tips on the market that will fit different brands of sprayers, such as these from Mudder, or from Jebower in a massive range of sizes from 209 to 621.

Q: What is a Suitable Automotive Spray Gun Tip Size?

This depends on the viscosity of the medium you are spraying. Many spray tips for guns used in the automotive industry are measured in mm, so as a general guide:

  • Use 1.7 to 2.2 mm for heavy primers and surfacers.
  • A 1.4 to 1.6 mm works well for basecoats.
  • 1.3 to 1.7 mm will cover you for a variety of clearcoats.
  • Single-stage urethanes and sealers spray best with 1.4 to 1.6-mm nozzles. Heavy-bodied primers and primer surfacers work best when you use a nozzle size of 1.7 to 2.2.
Q: What is the Best Spray Tip for Doors?

If you are spraying a single door in situ, then a 310 fine finish tip can handle the task. If you’re spraying several doors at once before installation, a 510 fine finish tip is most suitable.

Q: Are Paint Sprayer Tip Sizes the Same as Paint Sprayer Nozzle Sizes?

Tips and nozzles are the same things, just two different words. When making a paint sprayer nozzle selection, use the same charts as you would for spray tips.

Q: What Size Spray Tip for Elastomeric Materials?

Elastomeric coatings are heavy and viscous so require larger spray tips to dispense. Look for an aperture of between 0.021 and 0.039 inches.

Q: Is There a Specific Primer Spray Gun Tip Size?

Again, this depends on the thickness of the primer. Follow the manufacturer’s recommendations for the particular primer you’re using.
