Frequently Asked Questions

It fits professional/industrial Graco airless sprayers that accept Silver Flat Tip geometry and support a 0.045" orifice size at working pressure. Check your sprayer’s manual for the “maximum tip size” specification and ensure your gun/guard are compatible.

The 0.045" orifice is often used for heavier coatings and high-build applications where high flow is desired. Always follow coating manufacturer guidance and confirm your sprayer can maintain proper pressure/flow for atomization.

The Silver Flat Tip is a flat-fan style tip. Always ensure the tip/guard system you use matches the tip style specified by the gun/guard manufacturer.

Use adequate hose ID, keep filters clean, strain coatings, and start at the lowest pressure that provides a full, even fan. Increase pressure only as needed to reduce overspray and tip wear.
