The Multiquip 910021003 Copper Washer MQC-100,180 is a genuine OEM replacement designed for MQC-100 series concrete pumps. As a direct OEM component sourced through Multiquip's authorized parts network, 910021003 delivers the exact material grade and dimensional tolerancing required to maintain a proper seal in demanding concrete pumping applications. This washer is confirmed for MQC-100 series equipment, giving you confidence you are installing the correct part the first time. Keep a spare on hand — copper washers are a routine service item and having the right OEM part available keeps your pump running without unplanned delays.
Key Features
- OEM Copper Material Grade — Manufactured to Multiquip's original copper specification, ensuring correct compressibility and seal integrity under hydraulic and fluid system pressures typical of concrete pump operation.
- Direct Drop-In Replacement — Matches the original washer profile for straightforward installation with no rework to mating surfaces or fasteners.
- Confirmed Fitment for MQC-100 Series — Verified for MQC-100 cycloidal-drive concrete pumps, so you can order with confidence against your machine's parts list.
- Leak Prevention at Fluid Connections — A correctly seated copper washer maintains a compression seal at critical fluid joints; a worn or damaged washer risks fluid weeping, pressure loss, and contamination at the connection point.
- Genuine OEM Part — Supplied as an authorized Multiquip OEM component, meaning it meets the same production standards as the washer originally installed at the factory.
A copper washer serves as a deformable sealing element at threaded fluid connections and fittings. When tightened, the soft copper compresses slightly against the mating surfaces, creating a leak-free metal-to-metal seal capable of withstanding fluid pressure and minor surface irregularities. Over time and through repeated service cycles, copper washers can fatigue, crack, or lose their ability to compress adequately, leading to seepage or pressure drop at the joint. Replacing a worn copper washer with the correct OEM part — such as Multiquip 910021003 — restores the integrity of that connection and prevents more serious fluid system issues downstream.
