A tip piece for a sprayer includes a tip body extending between a first end and a second end. A passage extends inside the tip body from the first end to a terminal end between the first end and the second end of the tip body. A nozzle extends into the tip body from the second end of the tip body and intersects the terminal end of the passage to form an orifice. A rounded interface is formed on a perimeter of the orifice between the nozzle and the terminal end of the passage.
