Part number 257672 is a genuine OEM main wiper for 20-liter (5-gallon) platens used in Graco Supply Systems, including the D200, D200s, D60, S20, and L20c ram units. The main wiper forms the primary seal between the platen edge and the inner pail wall, preventing air ingestion, stopping material bypass, and maximizing fluid transfer. Worn wipers are a direct cause of fluid squeezing past the platen, loss of prime, and inconsistent pump pressure. This genuine replacement restores proper platen sealing and reliable system performance.
