The Multiquip EM16465 Piston Cup Spacer is a genuine OEM component designed for the LS-series hydraulic-driven concrete pump lineup, including the LS300, LS300G, LS300GK, LS300P, LS-40, LS40D, LS400, LS450, LS40TD, LS50TD, LS60TD, LS500, LS600, and LS600P models. As an authorized Multiquip OEM part, the part is manufactured to exact design specifications, ensuring proper fit and function within the concrete pump's piston assembly. DHS Equipment supplies this part direct from Multiquip's OEM inventory, so you can order with confidence knowing you are receiving the correct component for your machine.
Key Features
- Genuine OEM Tolerancing — Manufactured to Multiquip's original dimensional specifications for the piston assembly, ensuring the spacer seats correctly and maintains proper piston cup compression.
- Direct-Fit Replacement — Engineered as a drop-in fit for the LS-series concrete pump piston circuit, requiring no machining or modification to the cylinder bore or piston rod.
- Broad LS-Series Compatibility — Confirmed fitment across the LS300, LS400, LS450, LS500, LS600, LS40TD, LS50TD, LS60TD, and LS600P concrete pump models.
- Maintains Pumping Pressure Integrity — A correctly installed piston cup spacer ensures consistent piston stroke geometry, helping the pump maintain steady concrete output pressure and volume.
- Sealing System Protection — Proper spacer dimension prevents piston cup distortion and uneven wear, extending the service life of surrounding seals and reducing the frequency of piston assembly rebuilds.
The piston cup spacer is a precision component within the concrete pump's hydraulic piston assembly. It sits between the piston cup and the piston body, maintaining the correct axial position and compression of the cup seal against the cylinder wall. When this spacer is worn, deformed, or incorrectly sized, the piston cup can shift out of alignment — causing pressure loss, inconsistent concrete delivery, or accelerated seal wear that leads to internal fluid bypass and pump inefficiency.
