The Multiquip EM512877 Straight Adaptor is a genuine OEM component designed for LS300, LS400, LS500, LS600, and MQ600H series equipment. As a direct OEM replacement, EM512877 is manufactured to the same specifications as the original part, ensuring a correct connection every time. This adaptor fits across a wide range of Multiquip hydraulic-driven concrete pump models including the LS300, LS300P, LS300G, LS300GK, LS400, LS500, LS600, LS600P, LS40D, LS40TD, LS50TD, and LS60TD, as well as MQ600H, MQ600HTB, and MQ600HTP trash pump units. Sourced directly from Multiquip, this part is backed by OEM confidence and is sold by DHS Equipment to keep your operation running without compromise.
Key Features
- Genuine OEM Construction — Machined to original Multiquip tolerances for a secure, leak-free hydraulic or fluid line connection with no guesswork.
- Inline Straight Connection — Provides a direct, in-line coupling between fluid or hydraulic lines, maintaining proper flow path alignment within the pump system.
- Broad Model Compatibility — Fits LS300, LS400, LS500, LS600, LS40D, LS40TD, LS50TD, LS60TD series concrete pumps and MQ600H series trash pumps.
- Sustained System Pressure — A correctly seated adaptor maintains line integrity under operating pressure; a worn or loose adaptor can cause fluid loss, pressure drop, and pump performance issues.
- Fluid System Safety — Proper sealing at hydraulic and fluid line connections prevents uncontrolled leaks, protecting both operators and surrounding equipment on the worksite.
A straight adaptor serves as an inline connector between two fluid or hydraulic lines, allowing them to join along the same axis without a change in direction. In concrete pump and high-volume trash pump applications, this fitting plays a critical role in maintaining sealed, pressurized fluid pathways — whether in a hydraulic circuit or a pump discharge and priming system. When an adaptor cracks, corrodes, or develops thread damage, the result is fluid leakage, loss of system pressure, and potential pump failure, making timely replacement with a genuine OEM part essential to continued operation.
