Key Features
- Genuine OEM Integrity — Manufactured to Multiquip's exact tolerances for the LS-series hydraulic concrete pump line, ensuring correct thread engagement, port sizing, and sealing surface alignment.
- Direct-Connect Replacement — Engineered to mate with existing hydraulic or fluid circuit connections on compatible LS-series pumps with no rework to surrounding components.
- Broad LS-Series Fitment — Confirmed for LS40D, LS40TD, LS50TD, LS60TD, LS300G, LS300GK, LS400, LS500, LS600, and LS600P concrete pump models.
- Pump System Performance — A correctly fitted adapter maintains leak-free fluid or hydraulic flow within the pump circuit; a worn or improperly fitted adapter can cause pressure loss, fluid leaks, and pump output inconsistencies on the pour.
- Pressure-Critical Application — On concrete pump systems operating under significant hydraulic pressure, using an OEM-spec adapter helps maintain rated system pressure and reduces the risk of joint failure under load.
An adapter in a concrete pump system serves as a threaded or machined fitting that connects two fluid or hydraulic circuit components with differing port sizes, thread types, or configurations. On LS-series hydraulic-driven concrete pumps, these adapters are integral to maintaining sealed, pressure-rated connections throughout the hydraulic circuit that drives piston action and concrete displacement. When an adapter fails through thread damage, corrosion, or cracking, it can result in hydraulic fluid leaks, loss of system pressure, and interruption of concrete flow — making prompt replacement with the correct OEM part essential to keeping the pump operating at rated capacity.
