Frequently Asked Questions

The first digit represents half of the spray fan width, meaning the tip produces an approximately 6–8 inch spray pattern. The last two digits indicate the 0.021 inch orifice size, which determines the amount of coating that flows through the tip.

This spray tip is suitable for medium to heavy coatings such as latex paint, primers, and thicker architectural coatings. The larger orifice allows higher material flow for efficient coverage.

The tip is compatible with most Graco airless sprayers that use standard Uni-Tip or flat tip guard assemblies. Always verify compatibility with your spray gun model before installation.

The spray tip determines the fan width, spray pattern, and material flow rate. Choosing the correct tip helps achieve better finish quality and efficient paint coverage.
