The Multiquip EM16828 Piston Cup Spacer LST25 is a genuine OEM component designed for the LST25 series concrete pump. As a factory-sourced part, EM16828 meets the exact tolerances required for proper piston cup alignment and sealing within the pumping cylinder. This spacer is a direct replacement for the original and is confirmed to fit the LST25 concrete pump. Sourcing the correct OEM spacer keeps your pump operating at full output capacity and prevents premature wear on adjacent sealing components.
Key Features
- Genuine OEM Tolerancing — Manufactured to the exact dimensional spec of the original, ensuring proper compression and seating of the piston cup assembly within the cylinder bore.
- Direct Drop-In Replacement — Engineered to replace the original spacer on LST25 concrete pumps without modification to surrounding components or hardware.
- Confirmed LST25 Fitment — Specifically validated for the Multiquip LST25 hydraulic-driven concrete pump series.
- Protects Piston Cup Integrity — Correct spacer positioning maintains uniform piston cup contact, preventing bypass, pressure loss, and accelerated seal wear during pumping cycles.
- Hydraulic System Compliance — Using the correct OEM spacer in the piston assembly helps maintain consistent hydraulic pressure output, which is critical for safe and controlled concrete delivery.
The piston cup spacer sits within the pumping cylinder and maintains the correct axial position of the piston cup seal against the cylinder wall. This precise positioning is what allows the piston to generate consistent hydraulic pressure with every stroke, pushing concrete through the delivery line at a controlled rate. When this spacer is worn, damaged, or incorrectly sized, the piston cup loses its sealing contact, leading to pressure drop, material bypass, and increased wear across the entire piston assembly.
