This is Graco’s Heavy Duty Reverse-A-Clean (HD RAC) spray tip GHD419, which has a 0.19 inch orifice size and 0.38 GPM flow rate that produces a 8–10 inch fan width spray. The HD RAC spray tip precedes the XHD series tips and with the correct seals (can be purchased separately) will work in both the GHD and XHD tip guard. These tips offer the ideal way to clear plugs quickly and easily by simply reversing the SwitchTip, then triggering the gun.
