Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design specifications, ensuring the piston adapter delivers the correct dimensional tolerances needed for proper sealing and load transfer within the concrete pump cylinder.
- Direct Drop-In Replacement — Engineered to replace the original component without rework, aligning correctly with the piston and cylinder bore in the LS300 pump assembly.
- Confirmed Fitment — Verified for the LS300G and LS300GK hydraulic-driven concrete pump models.
- Sustained Pumping Pressure — A properly functioning piston adapter maintains consistent force transfer between the hydraulic drive and the concrete piston, supporting steady output pressure and uninterrupted material flow.
- Wear-Critical Component — The piston adapter is subject to high cyclic loads during operation; replacing a worn or damaged adapter promptly prevents accelerated wear on adjacent cylinder and piston components.
The piston adapter serves as the mechanical interface between the hydraulic drive piston and the concrete-pumping piston inside the pump cylinder. It transmits the force generated by the hydraulic system into the concrete delivery stroke, making it a critical load-bearing component in the pumping circuit. When this adapter wears, cracks, or becomes misaligned, pumping efficiency drops, output pressure becomes inconsistent, and surrounding cylinder components can suffer accelerated damage.
