Multiquip EM514920 Main Cylinder Hydraulic Hose

The Multiquip EM514920 is a genuine OEM Main Cylinder Hydraulic Hose designed for LS-series hydraulic-driven concrete pumps, including the LS600P, LS300P, LS600, LS500, LS400, LS50TD, LS40TD, LS60TD, and LS40D. As a direct OEM replacement, EM514920 is manufactured to the exact pressure ratings, diameter, and end-fitting specifications of the original hose, ensuring a correct installation without modification. Sourced directly through Multiquip's authorized parts network, this hose ships as a true like-for-like replacement for the main cylinder circuit on these machines.

Key Features

• Genuine OEM Pressure Rating — Built to the original hydraulic pressure specifications for the main cylinder circuit, maintaining safe and consistent pumping output across the LS-series lineup.
• Direct End-Fitting Compatibility — End fittings match the original port connections on the main cylinder assembly, allowing straightforward installation without adapters or rework.
• Broad LS-Series Fitment — Confirmed fit for LS600P, LS300P, LS600, LS500, LS400, LS50TD, LS40TD, LS60TD, and LS40D Mayco hydraulic concrete pump models.
• High-Cycle Hydraulic Durability — Constructed to withstand the continuous pressure cycling demands of a concrete pump's main cylinder, where hose failure leads to immediate loss of pumping function.
• Hydraulic System Integrity — A correctly rated hose prevents pressure loss and fluid leaks in the main cylinder circuit, protecting downstream hydraulic components from cavitation and wear.

The main cylinder hydraulic hose carries pressurized hydraulic fluid between the pump's power unit and the main pumping cylinders, providing the force needed to push concrete through the delivery line. Without a properly functioning hose, the hydraulic circuit cannot maintain the pressure required to drive the pistons, resulting in reduced output or a complete loss of pumping capability. A cracked, worn, or leaking hose also introduces contamination risk into the hydraulic system, which can cause accelerated wear across valves, seals, and cylinder components.
