The Multiquip 05278401 Sealing Ring is a genuine OEM component designed for MVH408DZ and MVH308DZ reversible plate compactors. Sourced directly from Multiquip, this sealing ring matches the original specification fitted at the factory, ensuring a proper, leak-free installation with no guesswork on fitment. If you're servicing an MVH308DZ or MVH408DZ and need a sealing ring you can trust, the 05278401 is the correct OEM part for the job.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Multiquip's original material and dimensional specification, delivering the compression and sealing performance the MVH series was engineered around.
- Direct Drop-In Replacement — Designed to seat exactly as the original, making reinstallation straightforward during routine service or overhaul of the compactor's fluid or hydraulic circuit.
- Confirmed Fitment for MVH Series — Verified compatible with the MVH308DZ and MVH408DZ reversible heavy-duty plate compactors.
- Prevents Fluid Loss and Contamination — A worn or damaged sealing ring allows fluid to escape or contaminants to enter, which can accelerate internal wear and compromise compaction output. Replacing it promptly keeps the machine running at full capacity.
- Fuel and Fluid System Safety — Proper sealing is critical in fuel and hydraulic circuits; a correctly installed OEM sealing ring reduces the risk of leaks that could create a fire or operational hazard on the worksite.
A sealing ring creates a pressure-tight barrier between mating components in a fluid circuit — whether in a fuel system, hydraulic system, or lubrication passage. Its job is to prevent fluid from leaking past a joint or fitting while also keeping outside contaminants from entering the system. When a sealing ring degrades, cracks, or loses its compression set, leaks develop that can starve components of lubrication or hydraulic pressure, leading to accelerated wear or sudden loss of function. Replacing it with the correct OEM part restores the original sealing performance and protects the surrounding components from damage.
