About the Graco 102960 Piston Cup Packing
The Graco 102960 Piston Cup Packing is an OEM sealing component that sits on the pump piston to maintain high-pressure sealing, reduce internal bypass, and help deliver a consistent spray pattern. A worn cup packing can cause pressure loss, pulsation, and premature wear of other pump parts. Replacing it at the first signs of leakage or pressure instability restores pump efficiency and extends overall pump life.
Key Features
- OEM fit for reliable sealing and performance
- Helps maintain spray pressure and pattern quality
- Reduces internal leakage and wear on mating components
- Supports smoother priming and steady material delivery
