The Graco RAC X LP Spray Tip LP517 is a low-pressure spray nozzle designed for professional and demanding painting tasks. This high-quality and durable spray nozzle ensures a consistent spray pattern over long periods and is suitable for walls, ceilings, and floors. It works particularly well with wall paints, latex, and other dispersion paints. The nozzle features SmartTip technology, which allows spraying at lower pressures, resulting in reduced tailing (overspray edges) and a smoother finish. The low-pressure operation also contributes to less wear and extends the nozzle's lifespan. The LP517 model has an orifice size of 0.017 inches (0.43 mm) with a spray pattern width of 10-12 inches (254-305 mm) and delivers a 10-inch wide spray pattern with a new nozzle. To determine when to replace it, measure the spray pattern width. The LP517 is considered worn and should be replaced when the width decreases from 10 inches to 8 inches to maintain efficiency and avoid increased paint consumption or extended project times. The nozzle is made from durable materials to withstand regular use with various coatings. Flow rates are specified with water at 138 bar (13.8 MPa, 2000 psi), with higher viscosity paints reducing the flow. This spray nozzle is part of the Graco RAC X SwitchTips series, developed for users seeking reliable performance and consistent results in painting projects.
