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.

Frequently Asked Questions

Generally yes—provided your spray gun uses a flat-tip guard and your sprayer supports a 0.031" orifice for the coating you plan to spray. Always confirm gun/guard type and machine capacity.

Base the choice on material viscosity, desired flow, and your sprayer’s supported tip size. Larger orifices flow more but demand more pump output; smaller orifices improve fine control with thinner coatings.

Always relieve pressure before handling, keep the tip clean, and replace when edges round off or tails appear. Verify seals/gaskets in the tip guard and keep filters appropriate for your coating.
