The Multiquip 50000800 is a genuine OEM Copper Washer 4M40L designed for the MVH508DZ reversible plate compactor and RAMMAX roller models including RW1404, RW1404MR, and RW1504HF. As a factory-sourced component, it meets the exact material and dimensional standards set by Multiquip for these machines. DHS Equipment supplies this part direct, so you can be confident you are receiving the correct washer for your equipment. Verify your model code against the fitment list before ordering to ensure compatibility with your specific serial number range.
Key Features
- Genuine Copper Construction — Soft copper material provides the correct crush and sealing properties required for leak-free joints, unlike steel or plated substitutes.
- Exact OEM Specification — Sourced directly from Multiquip as part number 50000800, matching the original washer in size, thickness, and thread compatibility for a drop-in installation.
- Broad Fitment Coverage — Compatible with MVH508DZ plate compactor and RW1404, RW1404MR, and RW1504HF RAMMAX roller models across specific serial number ranges.
- Sealing Integrity — A correctly seated copper washer maintains proper fluid containment; a worn or damaged washer leads to seepage, contamination, and potential component damage.
- Serial Number Range Awareness — Fitment for RW1404MR includes units from S/N 326075 and up, and RW1504HF covers units up to S/N 1534188 — confirm your serial number before ordering.
A copper washer functions as a compressible sealing element used at threaded fastener joints, drain plugs, and hydraulic or fluid fittings. When torqued into position, the soft copper deforms slightly to fill microscopic surface irregularities, creating a metal-to-metal seal that resists fluid leakage under pressure and temperature cycling. Over time, repeated removal and reinstallation causes the washer to harden and lose its ability to conform to the mating surfaces, resulting in seeps or leaks at the joint — making replacement at each service interval the recommended practice.
