The Graco 01/0055/89 Piston 10.000 x 0.194 NYL is a precision-engineered replacement piston designed for use in Graco airless paint sprayer pump assemblies. Manufactured from durable nylon (NYL), it delivers a balance of strength, reduced friction, and wear resistance to ensure smooth pumping performance under high-pressure operating conditions.
This piston plays a critical role in the fluid delivery system of airless sprayers, helping maintain consistent spray patterns, stable pressure output, and reliable operation in demanding professional painting applications.
The Graco 01/0055/89 Piston 10.000 x 0.194 NYL is a cylindrical pump component used inside Graco airless spray pump systems. It is responsible for creating the reciprocating motion that draws coating material into the pump chamber and pushes it out under high pressure. The “10.000 x 0.194” specification refers to its precise dimensional configuration, ensuring correct fit and sealing performance within compatible pump housings.
Constructed from nylon (NYL), this piston is designed to reduce internal wear, improve chemical resistance, and extend service life in continuous-use environments.
