Dedicating time to the selection of the Graco airless nozzle is key to performing a job correctly and giving it the professional finish that Graco guarantees. There are several aspects to consider when choosing one of the multiple nozzles that Graco offers, however today we will focus on the nozzle number. If we do not use the correct nozzle step the material may suffer more wear and we will not achieve a professional work result.

Which tip size is best for your application?

Interpret the code of Graco reversible airless tips.

To know which tip to choose, for a concrete painting activity, it is essential to know how to interpret the digit that appears on the Graco airless tip. The three-digit code displayed on Graco nozzles contains key information for selection.

The first digit of the Graco reversible airless tip indicates the fan width. The approximate width to which the airless gun will spray at a distance of 30 cm is obtained by multiplying this number by 5. The larger the first number, the wider the fan and the larger the area to be sprayed.

The last two digits indicate the size of the tip hole in thousandths of an inch. The larger the number, the larger the orifice and , therefore, the greater the flow of paint will spray the gun.

Material to be sprayed and application

The choice of one number or another will depend on the material used and the application

wood or metal	For enamels and paints, look for small holes between 0.009" and 0.015".
Varnishes and dyes	Require small holes.
viscous materials	Use tips with larger holes.
primers	They need a smaller hole size than the one that will be used for painting.

The following table will help you choose the right tip for each specific application and product.

To know which is the nozzle that best suits the paint application it is important to try several.

Is the powdered material too thick?
Use a smaller nozzle hole (515 instead of 517) or increase the spray angle (717 instead of 517).

Is the powdered material too fluid?
Use a larger nozzle hole (519 instead of 517) or reduce the spray angle (317 instead of 517).

If you choose the right nozzle pitch, not only will you get a better job, but you will also extend the life of your sprayer. Contact with us and we will advise you on what you need.
