but GRACO pistons for similar applications are typically made from durable materials such as UHMW (Ultra High Molecular Weight) polyethylene or other engineered plastics for longevity and resistance to wear[1][3]
Stainless steel pump body
Regularly inspect for wear and replace as needed to maintain system efficiency
and maintenance-friendly grease injection
Used in GRACO pumps and fluid handling systems where chemical and heat resistance are required for reliable sealing and long service life
