Precision UHMW HD piston designed to maintain stable pressure and smooth reciprocating action in compatible Graco airless pump assemblies.
The Graco 01/0055-1/88 Piston UHMW HD 10.000 x 0.194 is designed for select Graco high-pressure airless paint sprayer pump assemblies that utilize a 10.000" piston system with 0.194 specification tolerances.
The Graco 01/0055-1/88 is a precision-engineered piston component manufactured for high-pressure fluid handling systems. Built using UHMW HD (Ultra-High Molecular Weight High Density material), it is designed to deliver exceptional wear resistance, reduced friction, and long service life in demanding airless spray applications.
With a dimension specification of 10.000 x 0.194, this piston ensures accurate reciprocating motion inside Graco pump cylinders, maintaining consistent pressure output and optimal spray performance. It is commonly used in professional-grade painting, coating, and industrial finishing equipment.
This piston is a critical wear part that directly impacts pump efficiency, sealing integrity, and overall system reliability in Graco airless sprayers.
This piston is used in professional painting contractors, industrial coating systems, construction equipment maintenance, and large-scale surface finishing operations where Graco airless spray technology is deployed.
