Multiquip EM806438 Adapter Piston - OEM Replacement Part for Concrete Pumps

The piston adapter is a critical hydraulic interface component in Multiquip concrete pumps, connecting the hydraulic piston assembly to the material cylinder for precise pumping action. This component ensures proper alignment and force transfer during the pumping cycle, directly affecting output consistency and equipment reliability.

Designed specifically for Multiquip LS-Series concrete pumps, this adapter maintains the tight tolerances required for high-pressure concrete delivery. Regular inspection of the piston adapter during routine maintenance intervals helps prevent hydraulic fluid leaks, reduces wear on adjacent components, and ensures optimal pumping performance. Operators should monitor for signs of wear including irregular pumping action, pressure fluctuations, or visible damage during standard maintenance procedures outlined in the equipment operation manual.

Compatible with the following Multiquip concrete pump models:

• LS300G (Zenith Z428 Gasoline Engine)
• LS300GK (Kubota WG3800-G-E3 Gasoline Engine)
• LS450
