What is a 515 tip used for?

The Ultimate Guide to Paint Spray Tips & Sizing Charts [2022]

Spray tip size is designated by three numbers. Take the first digit; double it and this will give you the width of the spray fan in inches.

Yes, even in Australia, we still use inches for this measurement.

For example, a 515 tip will give you a spray fan pattern 10 inches wide (2 x 5) when the sprayer is approximately 12 inches (30 cms) from the surface.

A 315 tip will produce a 6-inch wide spray fan, a 413 tip will produce an 8 inch and so on.

This is a general guide because the fan width may vary slightly depending on the sprayer pressure and material choice by up to 2 inches (5cms).

Tip Orifice

The tip orifice is where final paint atomisation occurs. The last two digits indicate the size of this orifice in thousandths of an inch.

Thus, a 515 tip denotes an orifice measuring 15 thousandths of an inch in diameter.

Tip Size

The size of this opening controls how much coating material can flow out through the tip.

The larger the orifice, the more paint can come through it. The amount of pressure used will also influence this. Higher pressures will force more material through the orifice.

But what happens when you compare two tips with the same fan width but with different orifice sizes?

Let’s take an example.

A 515 tip compared with a 523 tip. Both tips will spray a pattern 10 inches wide but the 523 tip will produce a thicker coating provided you use the same sprayer pressure and hand speed.

On the other hand, keeping the orifice size the same and increasing the fan width allows you to spread the same amount of material over a wider area.

When it comes to choosing tips, you should start by checking the coating manufacturer’s instructions; they have researched optimum tip sizes for the viscosity of their particular products.

Having said that, the range of tip sizes available allows you almost infinite control of your spraying finish and quality.
