The Multiquip EM16816 Steel Insert Ring is a genuine OEM component designed for LS-series hydraulic-driven concrete pumps including the LS300GK, LS300G, LS300P, LS600P, LS60TD, LS50TD, LS40TD, LS40D, LS300, LS400, LS500, and LS600. As a direct Multiquip OEM part, the EM16816 is manufactured to the original design tolerances, ensuring a proper seat and seal within the pump assembly. Sourced directly through authorized distribution, this ring is a stock replacement you can install with confidence on your Mayco or Multiquip LS-series concrete pump.
Key Features
- OEM Steel Construction — Manufactured to the original hardness and dimensional specification required for high-pressure concrete pump service, not a softened or undersized substitute.
- Direct Drop-In Fit — Engineered to seat correctly in the original bore or housing without rework, maintaining proper contact and compression against mating components.
- Broad LS-Series Compatibility — Fits a wide range of hydraulic-driven Multiquip and Mayco concrete pump models including LS300GK, LS300G, LS300P, LS600P, LS60TD, LS50TD, LS40TD, LS40D, LS300, LS400, LS500, and LS600.
- Maintains Pumping Integrity — A correctly fitted steel insert ring keeps internal pump passages aligned and sealed, supporting consistent mix flow and output pressure at the nozzle.
- Genuine Multiquip OEM Part — Backed by Multiquip's OEM quality program, this part carries the correct part number EM16816 for verified fitment on LS-series units.
The steel insert ring is a precision-machined component seated within the pump's internal housing to reinforce critical bore surfaces and maintain alignment between moving or mating parts under high-pressure pumping cycles. In concrete pump applications, these rings resist the abrasive wear caused by moving aggregate-laden mix and sustain the structural integrity of the bore seat over time. When a steel insert ring is worn, cracked, or improperly seated, the pump can develop internal leakage, pressure loss, or uneven wear on adjacent components — all of which compromise output and increase the risk of unplanned service.
