Description
The Graco 163931 Silver Flat Tip, 931 is a precision airless tip engineered for consistent coverage and reliable atomization. Its 0.031" orifice supports medium-to-high flow materials while maintaining a broad, even fan. Ideal for large surface areas and architectural or industrial coatings when a clean flat-tip pattern is preferred.
Selection & Usage Notes
- Match the 0.031" orifice to your sprayer’s maximum supported tip size and the coating’s viscosity.
- Ensure your spray gun and guard are designed for flat tips (not reversible RAC-type only).
- Relieve pressure and follow safety procedures before installing or changing tips.
- Inspect for wear; a worn orifice can cause pattern tails, overspray, or poor edges.
