Keep your Wagner airless sprayer operating at peak efficiency with this genuine piston spring replacement designed for models such as the W180P and compatible electric power sprayers. The piston spring plays a crucial role in the pump assembly by helping return the piston after each stroke and creating the vacuum needed to draw paint into the pump chamber. Over time this spring can wear or break with heavy use, so replacing it helps maintain consistent paint flow, pressure and overall spray performance.
