The Multiquip 050300400 is a genuine OEM O-Ring S-40 designed for MVH-series reversible plate compactors. This sealing ring is a direct OEM replacement sourced from Multiquip and confirmed to fit MVH308, MVH408, and MVH508 models across diesel and gasoline engine variants, including the DZ, GH, DE, and GV configurations. Keeping the correct O-ring installed is essential to maintaining hydraulic and fluid system integrity on these heavy-duty reversible plates. Order with confidence knowing part number 050300400 is the factory-correct component for your machine.
Key Features
- Factory-Correct Sealing Material — Genuine OEM compound and dimensional spec ensure proper compression and sealing performance in reversible plate compactor hydraulic and fluid systems.
- Drop-In Replacement — Matches the S-40 groove profile exactly, seating securely without rework or modification to the mating surfaces.
- Broad MVH-Series Fitment — Confirmed for MVH308, MVH408, and MVH508 models across DZ, GH, DE, and GV variants — one part number covering the full reversible plate lineup.
- Prevents Fluid Leaks and Pressure Loss — A worn or damaged O-ring allows hydraulic fluid or lubricant to escape, leading to loss of compaction force and potential internal damage; replacing it promptly restores full operating pressure.
- Fuel and Fluid System Safety — Maintaining a properly seated O-ring prevents unintended fluid contact with hot engine components, supporting safe machine operation on the jobsite.
An O-ring is a circular elastomeric seal that sits within a machined groove to close the gap between two mating components, preventing fluid or air from escaping under pressure. On reversible plate compactors like the MVH series, O-rings are used throughout the hydraulic and lubrication circuits to maintain system pressure and keep contaminants out. When an O-ring degrades, cracks, or is compressed beyond its service life, it loses its ability to seal — resulting in fluid weeping, pressure drop, and accelerated wear on surrounding components. Replacing a failed O-ring promptly with the correct part is one of the most cost-effective maintenance steps an operator can take.
