Key benefits of using the Airless 517 nozzle
Using quality spare parts is the key to a long service life of your painting equipment and flawless work. This professional spray nozzle offers many advantages:

Exceptional efficiency and speed: The jet width between 250 and 300 mm enables extremely fast coverage of large areas, significantly reducing work process time and increasing your productivity.
Full, streak-free coverage: A precision-engineered 0.017-inch (0.43 mm) orifice ensures fine atomization of paint, preventing unwanted streaks and ensuring a smooth, professional application on the first pass.
Versatile use: The nozzle is ideal for working with a wide range of materials, from thicker wall paints to more demanding facade coatings and emulsions.
Reduced paint consumption: Optimized flow rate of 1.17 L/min reduces overspray, which means less wasted material, a cleaner work environment and less cleanup after the job is done.
High pressure durability: Designed to operate safely under extremely high pressure up to 5000 psi (345 bar), ensuring an extremely long service life even in daily professional use on demanding construction sites.

Frequently Asked Questions (FAQ)
1. Will this nozzle fit my Graco or Wagner spray gun?
Yes, this spray tip has a standard 11.1mm mounting pin diameter. This means it is fully compatible with most standard airless guns from Wagner, Graco and other established manufacturers on the market that use this established industry standard.
2. What exactly does the 517 marking on the nozzle mean?
The 517 designation consists of two parts that determine the spray characteristics. The first number "5" indicates the spray angle (50 degrees), which at the recommended distance of 30 cm from the wall creates a jet width of approximately 250 to 300 mm. The last two numbers "17" indicate the size of the nozzle opening itself, which is 0.017 inches or 0.43 mm, which determines the flow and suitability for certain paint densities.
3. How often does the airless nozzle need to be replaced?
The life of the nozzle depends primarily on the abrasiveness of the materials you are applying. Abrasive materials (such as some facade and silicate paints) wear the nozzle opening faster. When you notice that the width of the jet is visibly narrowing, that the paint consumption increases inexplicably, or uneven lines begin to appear at the edges of the jet, this is a clear sign that it is time to replace the nozzle with a new CG80770A spare nozzle.

Instructions for using the product:
• Before use, check that the 517 nozzle is compatible with your Wagner or Graco airless gun and that the nozzle, seal and mounting parts are undamaged.
• Turn off the airless sprayer and relieve pressure completely before installing, removing or cleaning the tip.
• Place the nozzle correctly in the gun holder together with the appropriate seal and secure it in accordance with the gun manufacturer's instructions.
• Before starting, check that the nozzle is correctly oriented and securely installed.
• When spraying, hold the gun approximately 30 cm from the surface and guide it evenly, parallel to the surface. For model 517, the stated spray width is approximately 250–300 mm.
• Move the gun at a steady speed. Do not stop in one place, as this may result in a too thick coating.
• For best results, make overlapping passes rather than trying to cover the entire surface in one pass.
• If the nozzle becomes clogged, first turn off the machine and relieve the pressure. If your system has a reversible nozzle, you can turn it to the unclogging position; some 517 models have this feature specifically designed for this purpose.
• After finishing work, remove the nozzle and clean it with a product that is compatible with the paint used.
• Before storing, check the nozzle and seal and keep them clean and protected.

Useful tips for work:
• The designation 517 means approximately 0.017" (0.43 mm) orifice. In this design, the stated jet width is approximately 250–300 mm and the flow rate is approximately 1.17 l/min.
• The nozzle is listed for acrylic, latex, silicate and emulsion paints. Always check the manufacturer's recommendations for the specific coating.
• For larger areas, the wider 517 pattern is practical, allowing for faster coverage. Graco also lists a maximum pattern width of approximately 254 mm (10") for its TrueAirless 517.
• Before painting, always check that the paint is properly prepared and filtered for the nozzle used.
• If the application is too thick, uneven or there is excessive overspray, adjust the distance, speed of movement and pressure according to the instructions for your device.
• Do not clean the nozzle with needles, wire or other hard objects that could damage the precision orifice.
• Clean the nozzle as soon as possible after use. Dried paint can cause clogging and uneven patterns.
• Check the nozzle regularly. A worn nozzle may start to deposit more material and create a poorer pattern.
• When replacing the nozzle, we also recommend inspecting or replacing the seal if it is worn.

Warnings:
• Airless spraying is carried out under very high pressure. The maximum working pressure listed for this nozzle is 345 bar (5000 psi).
• Never point the gun at yourself, other people or animals.
• Do not check for leaks by looking for them with your finger or hand. The high-pressure jet can cause serious damage to skin and tissue.
• Always perform the complete pressure relief procedure specified by the airless sprayer manufacturer before removing or cleaning the tip.
• Do not exceed the maximum allowable pressure of any part of the system.
• Do not use a damaged, deformed or severely worn nozzle.
• Check that the nozzle is properly attached before restoring pressure.
• When spraying, use safety glasses or a visor, protective gloves and appropriate respiratory protection depending on the coating used.
• Ensure sufficient ventilation of the room and follow the safety data sheet of the paint used.
• Coatings may contain substances that are hazardous if inhaled or come into contact with skin; follow the coating manufacturer's instructions.
• For flammable coatings, remove ignition sources and observe special requirements for the use of flammable substances.
• Keep children and other persons away from the work area during spraying.
• Keep the nozzle clean and protected from impacts, as even damage to the opening can affect the quality of the spray.

Same summary

The Wagner/Graco 517 airless spray nozzle is best suited for users looking for a reliable solution to replace worn or clogged nozzles on their painting equipment.

Answers to frequently asked questions

Is this spray nozzle suitable for all Wagner and Graco airless guns?

The 517 nozzle is not universal and is only compatible with certain Wagner and Graco airless gun models; always check the exact model number of your gun before purchasing.

How often should the spray nozzle be replaced for optimal performance?

The frequency of replacement depends on the intensity of use and the type of materials used. With regular use and thicker coatings, it makes sense to replace after several larger applications or when the spray pattern noticeably deteriorates.

What can I do if the nozzle does not fit my gun model?

If the product turns out to be incompatible, we recommend checking the descriptions of other nozzles, where a more accurate match to gun models is often given.

Are different nozzle sizes available depending on the type of coating?

Yes, the nozzle size should be adjusted to the type and density of the coating; the 517 nozzle is a common choice for medium-thick paint or varnish, but there are other sizes for very thin or very thick coatings.
