The Multiquip 03579800 is a genuine OEM Rubber Washer designed for MQ41TDH trash pumps, MDR-9D power trowels, and MVH502DSB and MVH502DSB2 reversible plate compactors. As a direct Multiquip OEM component, it is manufactured to the exact material grade and dimensional tolerances of the original part. Sourced direct from the Multiquip parts network, the part ensures a correct, straight-swapping installation with no guesswork on fit. Whether you are servicing a trash pump, a ride-on power trowel, or a heavy-duty reversible plate, this single part number covers all listed models.
Key Features
- OEM Rubber Compound Grade — Manufactured from the same rubber compound specification as the original, delivering the correct compression set and sealing characteristics for each application.
- Direct Drop-In Installation — Matches the original bore diameter, outer diameter, and thickness so it seats correctly without trimming or shimming.
- Broad Cross-Model Coverage — A single part number fits the MQ41TDH trash pump, MDR-9D power trowel, and MVH502DSB and MVH502DSB2 reversible plate compactors.
- Sealing and Vibration Isolation — Maintains the integrity of fastened joints under operational vibration, preventing fluid ingress and hardware loosening across very different machine types.
- Fuel and Fluid Resistance — Rubber compound withstands exposure to water, oil, and fuel that washers in pump and compactor environments routinely encounter.
A rubber washer acts as both a sealing element and a cushion between mating fastener surfaces. It compresses under clamping load to fill minor surface irregularities, blocking moisture and contaminants from migrating into the joint while also dampening vibration that could work a fastener loose over time. When a rubber washer hardens, cracks, or takes a permanent set, it loses that sealing and cushioning ability — allowing leaks, corrosion at the joint, and fastener loosening that can escalate into more serious mechanical problems if left unaddressed.
