Compatibility

RAC X LP SwitchTip — fits the Graco RAC X tip guard (RAC X HandTite Tip Guard) on RAC X-equipped airless sprayers. The reversible design lets the tip be rotated to clear a clog without removing it. Tip size is selected by material and required fan width; the LP series lowers the pressure needed for a clean spray pattern. Confirm the sprayer and tip guard are RAC X before ordering.
