The Multiquip 050300380 O-Ring S-38 is a genuine OEM seal designed for MVH-series reversible plate compactors, including MVH308, MVH408, and MVH508 models. As a direct OEM replacement, this O-ring meets the original design specifications Multiquip engineers built into these machines, ensuring a proper seal without improvisation or modification. Compatible across diesel and gasoline variants of the MVH308, MVH408, and MVH508 series — including DZ, GH, DE, and GV configurations — this part covers a wide range of MVH heavy-duty reversible plates in active service. Sourced directly from Multiquip, the 050300380 is the correct replacement when resealing hydraulic or fluid-carrying components on your compactor.
Key Features
- Genuine OEM Sealing Material — Manufactured to the original compound and dimensional spec for the S-38 profile, delivering the same compression and fluid resistance as the part it replaces.
- Drop-In Replacement — Sized and profiled to seat directly into the original groove without trimming or reworking the mating surfaces.
- Broad MVH Series Coverage — Fits MVH308, MVH408, and MVH508 models across DZ, GH, DE, and GV variants, making it a practical stock item for fleets running multiple MVH compactors.
- Leak Prevention — A correctly seated O-ring maintains fluid integrity in the compactor's hydraulic or lubrication circuit; a worn or cracked ring leads to seepage, pressure loss, and accelerated component wear.
- Fluid System Integrity — On reversible plate compactors, maintaining sealed fluid passages is critical to consistent vibration output and directional control — this part keeps those systems operating as designed.
An O-ring is a circular elastomeric seal used to prevent fluid or air from passing between mating components. In reversible plate compactors like the MVH series, O-rings are commonly found in hydraulic circuits, exciter housings, and fluid reservoirs, where they form a compression seal between joined parts. When an O-ring degrades — through heat cycling, chemical exposure, or age — it loses elasticity and begins to leak, which can result in hydraulic fluid loss, contamination, and eventual failure of the surrounding assembly. Replacing a worn O-ring promptly with the correct OEM part restores the seal and protects the integrity of the components around it.
