The Graco 16C650 Reservoir Seal is an OEM replacement seal designed for the material cup on select Graco handheld sprayers. It ensures a tight and reliable seal between the cup and lid, preventing material leakage and maintaining consistent spray performance.
This seal plays a key role in maintaining proper pressure inside the reservoir, helping the sprayer deliver smooth flow, proper priming, and steady atomization. If your sprayer is leaking around the cup area or losing prime, replacing the material-cup seal is often the correct solution.
