The Multiquip 8907428 Copper Washer 43E is a genuine OEM copper washer designed for the RW1403HF roller. As a direct OEM replacement, it meets the exact material and dimensional requirements specified for this machine, ensuring a proper seal and consistent performance in service. This part is sourced directly through Multiquip's authorized parts network and is confirmed compatible with the RW1403HF.
Key Features
- Pure Copper Construction — Copper's natural malleability allows the washer to conform and seat correctly under torque, providing an effective fluid seal that a steel or fiber washer cannot replicate in the same application.
- Genuine OEM Part — Sourced from Multiquip's authorized supply chain, this washer matches the original specification for grade, thickness, and inner diameter — no guesswork on fitment.
- Confirmed Fitment for RW1403HF — Designed specifically for the RW1403HF RAMMAX roller, so it drops into place without rework or adaptation.
- Prevents Fluid Leaks at Fastened Joints — A correctly seated copper washer maintains a leak-free connection at hydraulic or fluid-carrying fittings; a worn or crushed washer is a common source of seeps and slow leaks that compromise machine operation.
- Low-Cost Service Item, High-Impact Result — Replacing this washer during routine maintenance or a repair keeps joints sealed and avoids fluid loss that can lead to larger component damage over time.
A copper washer functions as a crush-type sealing element at threaded fittings, drain plugs, or hydraulic connections. When torqued into place, the soft copper deforms slightly to fill microscopic surface irregularities between mating faces, creating a reliable metal-to-metal seal against fluid or pressure loss. Over time, heat cycling and repeated removal can harden or damage the washer, causing it to lose its ability to seal — at which point replacement with a new OEM-spec washer is the correct fix.
