The Graco Fine Finish Low Pressure Tips spray up to 50% lower pressure with less over-spray, providing a soft spray fan pattern when spraying any material, to any surface. By spraying at half the pressure, it naturally increases the tip life by nearly double. These tips work well with any airless sprayers. Graco Fine Finish Low Pressure Airless Spray Tip Numbers Explained The first digit of the code, when doubled, tells you the fan width of the tip in inches when sprayed at a distance of 12 inches from the surface. The last two numbers in the tip designation indicate the size of the tip orifice in thousandths of an inch. The higher the number, the greater the flow rate when spraying. For example, a 517 tip provides more flow than a 515 tip.
