The Multiquip EM168161 Rubber Energizer Ring is a genuine OEM component designed for LS300GK, LS300G, LS300P, LS600P, and LS60TD hydraulic-driven concrete pumps. As a factory-sourced part, EM168161 is manufactured to the exact material grade and dimensional tolerances required by Multiquip for this pump family. Sourcing the correct energizer ring is critical — an improperly fitted or worn ring directly affects sealing integrity inside the pump's hydraulic circuit, leading to pressure loss and unplanned stoppages. DHS Equipment supplies this genuine OEM part to keep your concrete pump running at full output.

Key Features

  • OEM Rubber Compound Grade — Manufactured from the factory-specified rubber formulation to deliver the correct compression set and sealing force within the hydraulic circuit, not a generic elastomer substitute.
  • Direct-Fit Replacement — Dimensioned to drop into the original seat without alteration, maintaining proper energizer engagement against mating seals and surfaces.
  • Broad Concrete Pump Fitment — Compatible with LS300GK, LS300G, LS300P, LS600P, and LS60TD hydraulic-driven concrete pump models.
  • Maintains Hydraulic Sealing Performance — A correctly functioning energizer ring sustains consistent pressure behind the primary seal; a degraded ring allows bypass leakage that robs pump output and accelerates seal wear.
  • Pressure System Integrity — In hydraulic concrete pump applications, seal circuit failures can result in uncontrolled fluid discharge; using the correct OEM energizer ring supports safe, contained system operation.

An energizer ring is a secondary sealing element that sits behind a primary lip or face seal, applying a constant outward load to keep the primary seal firmly pressed against its running surface. In hydraulic concrete pumps, this preload is essential for maintaining circuit pressure across a wide range of operating temperatures and pressures. When the rubber compound fatigues, takes a permanent set, or cracks, it can no longer energize the primary seal effectively, causing internal bypass, reduced pumping pressure, and eventual seal failure that can contaminate hydraulic fluid or bring the pour to a halt.
