The Multiquip 363198 Oil Seal is a genuine OEM component designed for LS series hydraulic-driven concrete pumps, including the LS300, LS400, LS40D, LS40TD, LS500, LS50TD, LS600, and LS60TD. As a direct OEM replacement, this seal is manufactured to the exact material grade and compression specifications required by Multiquip, ensuring a proper fit within the pump's drive and hydraulic assemblies. Sourced directly through authorized channels, the 363198 is the correct part to specify when servicing your Mayco concrete pump. DHS Equipment stocks genuine Multiquip parts to help you get your LS series pump back in service quickly and correctly.
Key Features
- OEM Material Grade: — Manufactured to the exact elastomer and dimensional specification required for LS series concrete pump sealing surfaces, maintaining proper compression and fluid retention under hydraulic operating pressures.
- Drop-In Replacement: — Engineered to seat correctly in the original housing bore, requiring no machining or modification to the pump's drive or hydraulic assembly.
- Broad LS Series Compatibility: — Confirmed fitment across LS300, LS400, LS40D, LS40TD, LS500, LS50TD, LS600, and LS60TD hydraulic-driven concrete pump models.
- Prevents Hydraulic Fluid Loss: — A correctly installed oil seal keeps hydraulic fluid contained within the drive system, maintaining consistent pump output pressure and protecting internal components from contamination.
- Fluid Containment Safety: — Maintaining a sound oil seal prevents hydraulic fluid from leaking onto hot surfaces or the work area, supporting safe pump operation on active concrete placements.
An oil seal is a precision-fitted ring that prevents hydraulic or lubricating fluid from escaping around rotating shafts and between mating housings inside the pump's drive system. In a hydraulic-driven concrete pump like the LS series, the oil seal is critical to sustaining the pressure differential that drives the pumping mechanism — a worn or damaged seal allows fluid to bypass its seating surface, causing pressure loss, reduced concrete output, and potential contamination of surrounding components. Replacing a failed oil seal promptly with the correct OEM part restores proper hydraulic containment and protects the pump's internal assemblies from accelerated wear.
