The Multiquip 40023200 is a genuine OEM O-Ring 31x40x4.5 MVH-302D/ES79 designed for the ES79 and MVH-302D reversible plate compactors. As a direct Multiquip OEM component, 40023200 is manufactured to the exact material grade and dimensional tolerances required by the original equipment design, ensuring a proper compression seal without modification. DHS Equipment supplies this part with verified fitment for ES79 and MVH-302D series machines, so you can order with confidence and get your compactor back to work fast.
Key Features
- Precision-Dimensioned Sealing Material — Manufactured to the exact 31x40x4.5 mm profile required for a correct compression fit in the ES79 and MVH-302D hydraulic or fluid circuits.
- Genuine OEM Component — Sourced directly from Multiquip, this O-ring meets the same material and hardness specifications as the original part installed at the factory.
- Confirmed Fitment — Verified for MVH-302D and ES79 reversible plate compactors; use part number 40023200 to confirm compatibility before ordering.
- Leak-Free Operation — A correctly seated O-ring maintains fluid integrity in the compactor's system, preventing pressure loss that can lead to inconsistent vibration output or fluid contamination.
- Cost-Effective Seal Replacement — Replacing a worn or damaged O-ring at the first sign of seeping is far less costly than addressing downstream damage to pumps, valves, or internal housings.
An O-ring is a circular elastomeric seal used to close the gap between two mating surfaces, preventing fluid or air from escaping a pressurized system. In reversible plate compactors like the MVH-302D and ES79, O-rings are critical to keeping hydraulic or lubrication circuits sealed under the vibration and loading stress of continuous compaction work. When an O-ring degrades, hardens, or takes a compression set, it loses its ability to seal — leading to fluid leaks, pressure drop, and accelerated wear on surrounding components.
