The Multiquip 910030021 Bonded Washer Seal MQC180 is a genuine OEM bonded washer seal designed for the MQC-180 concrete pump. Sourced directly from Multiquip, this part meets the exact material and dimensional specifications required for a proper, leak-free installation on MQC-180 equipment. If you are servicing or rebuilding your concrete pump, using the correct OEM seal is critical to maintaining hydraulic integrity and preventing fluid loss under operating pressure. DHS Equipment stocks this part to keep your MQC-180 running at full capacity.
Key Features
- OEM-Grade Seal Material — Manufactured to Multiquip's bonded seal specifications, ensuring correct compression, chemical resistance, and sealing performance under the pressure demands of concrete pump operation.
- Direct Bolt-In Replacement — Dimensioned to fit the MQC-180 seating surface exactly, allowing straightforward installation without modification to mating components.
- Confirmed MQC-180 Fitment — Verified for use on the Multiquip MQC-180 cycloidal-drive concrete pump series.
- Leak Prevention Under Load — A worn or degraded bonded washer seal allows fluid bypass and pressure loss, which can compromise pump output and accelerate wear on surrounding components. A fresh OEM seal restores proper sealing performance.
- Fluid System Integrity — In a high-pressure concrete pump environment, even a minor seal failure can introduce contamination or cause dangerous pressure buildup — using the correct OEM-specified seal supports safe and consistent pump operation.
A bonded washer seal is a sealing fastener that combines a metal washer with a bonded rubber element, creating a dual-function component that provides both mechanical clamping force and a fluid-tight seal in a single part. In a concrete pump like the MQC-180, these seals are used at critical fluid connection points to prevent hydraulic fluid or other media from escaping under pressure. When a bonded washer seal deteriorates — through compression set, cracking, or chemical degradation — it loses its ability to form a reliable seal, leading to leaks, pressure drop, and potential damage to the pump's hydraulic system.
