Full details
The Graco TrueAirless Spray Tip - 311 is designed for DIYers and professionals seeking a precise spray for smaller, detailed projects. Its key benefit is the 6-inch narrow spray pattern, perfect for applications like fences, decks, and furniture with thinner materials. A potential caveat is its optimal performance with specific thinner coatings, requiring users to ensure material compatibility for best results.

FAQs
What type of materials is the Graco TrueAirless Spray Tip - 311 best for?
This tip is optimal for spraying thinner materials like semi-transparent stains, water sealers, lacquers, and polyurethanes. It is not recommended for heavy-bodied paints.
How do I know if my spray tip is clogged?
A clogged tip will result in an uneven spray pattern, spitting, or no material coming out at all. The reversible feature is designed to quickly clear most clogs.
What does the '311' in the product name mean?
The first digit ('3') indicates the fan width (3 x 2 inches = 6-inch fan width). The last two digits ('11') indicate the orifice size in thousandths of an inch (.011 inches).
Can I use this tip with any airless sprayer?
This tip is designed for Graco TrueAirless sprayers and systems. Ensure your sprayer can support the required pressure for this tip size.
How often should I replace the spray tip?
Replacement frequency depends on usage and the materials sprayed. Inspect the tip regularly; if the spray pattern becomes uneven or distorted, it's likely time for a replacement.
What is SoftSpray Technology?
SoftSpray Technology is a Graco feature that provides enhanced control over the spray pattern, allowing for easier blending of passes and a smoother, more professional finish, especially at lower pressures.
Troubleshooting
Uneven spray pattern or "tails"
Check for clogged passages in the tip. Use the reversible feature to clear it. Ensure the spray material is compatible and properly thinned. Verify correct sprayer pressure.
Tip clogs frequently
Ensure the material is properly filtered before use. Clean the intake strainer on the sprayer. Check if the material viscosity is too high for the tip's hole size.
Poor material atomization
Confirm the sprayer pressure is adequate for the tip size and material. Ensure the tip is not worn out. Check for any blockages or obstructions.
Leaking from the tip or gun
Ensure the tip is securely seated in the guard. Check the condition of the tip seal and guard O-rings. Tighten the guard slightly if necessary, but do not overtighten.

Care:
- Cleaning: After each use, remove the tip and flush it with the appropriate solvent (water for latex, mineral spirits for oil-based). Use the reversible feature to clear any residual material.
- Storage: Store the tip in a clean, dry place. Consider keeping it in its original packaging or a dedicated tip storage case.
- Inspection: Regularly inspect the tip for wear and tear. A worn tip can affect spray pattern quality and material flow.
