Graco LTX633 RAC X SwitchTip, a reversible (clog-clearing) airless spray tip, part number LTX633, with a 0.033 in. (0.84 mm) orifice and a 12 in. (304.8 mm) spray fan width. Maximum working pressure 4050 psi (280 bar). The tip number 633 encodes the size: the first digit (6) doubled gives the 12 in. fan width and the last two digits (33) give the 0.033 in. orifice. The spray pattern size measured on the Graco page is 12 to 14 in. The reversible design lets the tip be rotated to clear a clog without removing it. For use with RAC X HandTite Tip Guard.
