The Multiquip EM70860 is a genuine OEM Cup Holder Piston designed for hydraulic-driven concrete pump models including the LS300GK, LS300G, LS300P, LS600P, LS300, LS600, LS50TD, LS40TD, LS500, LS400, LS40D, and LS60TD. As a factory-sourced component, it meets the exact tolerances required to maintain consistent pumping pressure and output in demanding concrete placement applications. Sourced directly through Multiquip's OEM parts program, the EM70860 ensures you are installing the correct specification part the first time. DHS Equipment stocks this part to support contractors and operators who depend on their LS-series concrete pumps to perform without interruption.
Key Features
- Genuine OEM Tolerancing — Manufactured to Multiquip's exact piston specifications, ensuring proper sealing force and pressure retention within the pump cylinder bore.
- Direct Drop-In Replacement — Engineered to match the original cup holder piston geometry, allowing straightforward installation into the pump cylinder assembly.
- Broad LS-Series Compatibility — Fits a wide range of hydraulic concrete pump models including LS300GK, LS300G, LS300P, LS600P, LS50TD, LS40TD, LS60TD, and related variants.
- Sustained Output Pressure — A correctly seated cup holder piston maintains the pumping stroke efficiency that keeps concrete moving smoothly through the line; wear or failure leads to pressure loss and inconsistent delivery.
- Pressure System Integrity — In a hydraulic concrete pump, a worn or degraded piston can cause fluid bypass and uncontrolled pressure drops — replacing with a genuine OEM part protects the integrity of the hydraulic circuit.
The cup holder piston is a core reciprocating component inside the concrete pump cylinder assembly. It forms the sealing interface that converts hydraulic force into the pumping stroke, pushing concrete through the delivery line at consistent pressure. When the piston or its cup seals wear down, the pump loses stroke efficiency, resulting in pressure loss, reduced output, and potential damage to surrounding cylinder components.
