GRACO 184421 – UHMWPE Lower/Back-Up Wiper for 5 Gallon Wiper Plate Assemblies

GRACO 184421 is the UHMWPE (Ultra-High Molecular Weight Polyethylene) lower wiper used in GRACO’s 19 liter (5 gallon) wiper plate assemblies. It functions as a back-up wiper that sits beneath the primary contact wiper to provide secondary sealing and scraping against the pail wall, helping evacuate more material and extend the life of the primary wiper.
