The Multiquip EM923023 is a genuine OEM Flat Washer 5/16" designed for LS600P and LS300P hydraulic-driven concrete pumps. As a factory-sourced component, EM923023 matches the exact material grade, outer diameter, and thickness specified for these machines — ensuring proper load distribution and fastener security at every installation point. Sourced directly through Multiquip's OEM parts program, this washer is the correct choice when performing maintenance or repairs on LS-series concrete pump assemblies. DHS Equipment stocks genuine Multiquip replacement parts so you can keep your equipment running with confidence.
Key Features
- OEM-Matched Material and Dimensions — Manufactured to the exact 5/16" specification called out in Multiquip's parts documentation, ensuring correct load-bearing surface area and material hardness for the application.
- Drop-In Hardware Compatibility — Engineered to seat flush against the fastener and mating surface without shimming or modification, maintaining proper clamp force across bolted assemblies.
- Confirmed Fitment for LS-Series Concrete Pumps — Verified for use on LS600P and LS300P hydraulic-driven concrete pump models.
- Protects Fastener Integrity Under Load — A correctly sized flat washer distributes bolt tension evenly across the contact surface, preventing fastener pull-through, surface damage, and loosening under vibration.
- Genuine Multiquip OEM Part — Supplied as an authorized OEM component, so the part number, fitment, and specification are backed by Multiquip directly.
A flat washer serves as a load-distributing interface between a fastener — bolt, nut, or screw — and the surface it bears against. By spreading clamping force over a wider area, it prevents the fastener from pulling through softer materials, protects surface finishes, and maintains consistent bolt tension even when the machine is exposed to vibration or cyclical stress. On equipment like the LS600P and LS300P concrete pumps, where hydraulic pressure and mechanical loads are constantly in play, using the correct washer specification matters — an undersized or incorrect washer can lead to fastener loosening, surface deformation, or joint failure over time.
