Frequently Asked Questions

Fitment depends on your spray gun’s guard. If your gun uses a 7/8" flat tip holder/guard, this tip will fit. If your gun uses RAC 5 / RAC X tips, you’ll need the appropriate flat-tip guard to switch to this style.

The 0.039" orifice typically produces an ~18" fan at standard spray distance. Actual fan width/finish will vary by pressure, coating viscosity, temperature, and technique. Start at the lowest effective pressure and adjust gradually.

No. The 163939 listing is for the tip only. If you don’t have a flat-tip guard, purchase the correct 7/8" flat tip holder/guard separately to mount this tip to your gun.
