Graco RAC X Reversible Spray Tip

The Graco RAC X reversible tip is the business end of an airless spray system. It sets the fan width and the flow rate, so it controls how the paint lands on the surface and how hard the pump has to work. This listing covers four sizes: 519, 521, 619 and 621, so you can match the tip to the coating and the surface you are spraying.

Frequently Asked Questions

How do I read the tip number?

The first digit is the fan width code and the last two digits are the orifice size in thousandths of an inch. A 519 tip gives a moderate fan at a smaller orifice, while a 621 gives a wider fan with more flow. Pick the size to match the coating and the surface.

What does reversing the tip do?

When the tip clogs, you twist it 180 degrees in the guard and trigger the gun once. The pressure blows the blockage out through the reversed opening, and you twist it back and keep spraying. It turns a tip blockage into a five second fix.

Which size should I start with?

For most house paints, primers and topcoats, a 517 or 519 is a good starting point. If you are spraying thicker roof or elastomeric coatings, step up to the 619 or 621 for the higher flow they need.

How do I clean a RAC X tip?

Remove the tip from the guard and rinse it with the correct cleaning solvent, then use a soft brush to clear the orifice. Never use a metal pick that can scratch the carbide. A clean tip gives a consistent fan and a longer working life.

What does RAC X stand for?

RAC X is Graco’s reverse a clean system for spray tips. The tip reverses in the guard to clear blockages, and the X design indexes the tip so it seats in the correct position every time. It is the current standard across the Graco Contractor gun range.
