Graco LTX321 RAC X SwitchTip, a reversible (clog-clearing) airless spray tip, part number LTX321, with a 0.021 in. (0.53 mm) orifice and a 6 in. (152.4 mm) spray fan width. Maximum working pressure 4050 psi (280 bar). The tip number 321 encodes the size: the first digit (3) doubled gives the 6 in. fan width and the last two digits (21) give the 0.021 in. orifice. The spray pattern size measured on the Graco page is 6 to 8 in. The reversible design lets the tip be rotated to clear a clog without removing it. For use with RAC X HandTite Tip Guard.
