The Multiquip EM168161A Rubber Energizer Ring is a genuine OEM component designed for LS300GK, LS300G, LS300P, LS600P, and LS60TD series hydraulic concrete pumps. As a factory-sourced part, EM168161A meets the original design tolerances required to maintain proper sealing pressure and pumping consistency across the Mayco and Multiquip LS-series pump lineup. Sourced directly through an authorized Multiquip parts distributor, this ring is verified against the OEM parts catalog to confirm an exact application match. DHS Equipment stocks genuine Multiquip replacement parts to help you get your equipment back in service without guesswork.
Key Features
- Genuine OEM Rubber Compound — Manufactured to the original material specification, ensuring correct compression and elasticity under the pressure cycles of hydraulic concrete pump operation.
- Direct Drop-In Replacement — Engineered to the same dimensional profile as the original, seating correctly within the pump's energizer groove without rework or shimming.
- Broad LS-Series Compatibility — Confirmed fitment across LS300GK, LS300G, LS300P, LS600P, and LS60TD hydraulic concrete pump models.
- Maintains Sealing Integrity — A worn or degraded energizer ring allows pressure loss at the seal interface, leading to inconsistent concrete flow and accelerated wear on surrounding pump components.
- Pressure-System Safety — In a hydraulic concrete pump, maintaining correct seal energization is critical to preventing uncontrolled pressure release; using the correct OEM-spec rubber ring supports safe, controlled operation.
The rubber energizer ring is a secondary sealing element that works behind a primary seal face to apply consistent radial or axial load, keeping the seal energized and properly seated under operating pressure. In a hydraulic concrete pump, this component plays a critical role in maintaining the pressure differential required to move concrete smoothly through the delivery system. When the energizer ring degrades — through compression set, cracking, or chemical attack from pump lubricants — the primary seal loses its backing force, causing pressure drop, fluid bypass, and potentially abrupt seal failure that can interrupt the pour and damage downstream components.
