Frequently Asked Questions

This tip is designed for the Flat Tip Guard (220251) or an equivalent flat-tip guard. It is not a RAC-style reversible tip.

Compatibility is determined by the gun and guard, not a specific sprayer model list. If your gun accepts a flat-tip guard and your system supports 0.021 in tips up to 5000 psi, this tip will fit.

No. Silver Flat Tips are non-reversible flat tips and require a compatible flat-tip guard (e.g., 220251), not a RAC reversible guard.

Use with materials appropriate for a 0.021 in orifice and your sprayer’s capacity—commonly architectural paints and coatings. Always check coating TDS and perform a test spray.
