Frequently Asked Questions
It will fit when your spray gun/guard uses 7/8"-14 UNF and your system is rated to ≤ 5,000 psi. Check your gun manual to confirm the guard type. This is a flat (non-reversible) tip and needs a flat-tip guard (e.g., 220251).
No—this is a flat tip. RAC tips are reversible and require a RAC guard. Use the correct guard type for your system. If you currently have a RAC guard, you would need to switch to a flat-tip guard to use 163861.
The 0.061" orifice and wide fan are suited to heavier coatings and high-production work. Always test pattern/pressure with your coating and follow manufacturer recommendations.
