The Graco 17R291 Collar, Retaining, T3 is a precision-engineered mechanical retention component used within Graco’s T3 pump assemblies. Its primary function is to securely hold and stabilize internal pump parts in place, ensuring proper alignment and consistent operation under high-pressure material transfer conditions. This retaining collar is critical for maintaining system integrity, reducing internal movement, and supporting long-term pump durability in demanding coating and texture applications.
The retaining collar is a structural fastening element designed specifically for the Graco T3 pump platform. It plays an important role in locking pump components into position within the assembly, helping prevent wear caused by vibration, pressure fluctuation, and continuous industrial use. As part of the internal pump architecture, it contributes to stable fluid transfer performance and operational reliability in professional spray systems.
