The Multiquip EM802681 Plate Seal is a genuine OEM component designed for LS300GK, LS300G, LS300P, and LS600P hydraulic-driven concrete pumps. As a factory-sourced replacement, it meets the original material and dimensional specifications required to maintain a reliable, pressure-rated seal within the pump assembly. Sourced directly through authorized Multiquip distribution, part number EM802681 is the correct service replacement for these Mayco and LS-series units. If your pump is showing signs of fluid bypass, pressure loss, or visible leakage around the plate, this seal is the part to address it.
Key Features
- Genuine OEM Material Grade — Manufactured to Multiquip's original compound and hardness specifications for a seal that holds up under the high-pressure cycling demands of hydraulic concrete pump operation.
- Drop-In Service Replacement — Engineered to the same dimensional profile as the original, seating correctly against the plate interface without reworking or shimming the surrounding components.
- Confirmed Fitment — Verified for LS300GK, LS300G, LS300P, and LS600P hydraulic-driven concrete pump models.
- Pressure Integrity — A correctly installed plate seal prevents hydraulic fluid bypass and maintains consistent output pressure, keeping concrete delivery smooth and uninterrupted through the pumping cycle.
- Leak Prevention — Failed or worn seals allow fluid to migrate past the plate face, which can contaminate the concrete mix and damage adjacent hydraulic components if left unaddressed.
The plate seal forms a compression barrier between mating plate surfaces within the hydraulic circuit of the concrete pump. Its role is to prevent fluid from bypassing the intended flow path, which is critical for maintaining the pressure needed to move concrete consistently through the delivery system. When this seal degrades — through age, heat cycling, or abrasive contamination — pressure drops, output becomes erratic, and fluid leakage can accelerate wear on surrounding pump components.
