The Multiquip EM50423 Oil Seal 40X55X10 is a genuine OEM oil seal designed for QP2TZ and QP3TZ trash pumps and MVH408DZ and MVH308DZ heavy-duty reversible plate compactors. As a direct Multiquip OEM component, EM50423 is manufactured to the exact dimensional and material specifications required by these machines — ensuring a proper seating fit without modification. This seal is stocked and sold by DHS Equipment as an authorized Multiquip replacement part, so you can order with confidence knowing you are receiving the correct component for your equipment.
Key Features
- Precision-Dimensioned OEM Seal Material — Manufactured to the exact 40x55x10 mm profile specified by Multiquip, ensuring correct compression and lip contact against the mating shaft and bore surfaces.
- Drop-In Fitment Across Two Equipment Families — Verified fit for QP2TZ and QP3TZ trash pumps as well as MVH408DZ and MVH308DZ reversible plate compactors, covering multiple machine types with a single part number.
- Genuine Multiquip OEM Component — Sourced directly from Multiquip, this seal meets the same material grade and dimensional tolerances as the part installed at the factory — not an approximation.
- Protects Critical Rotating Assemblies — A properly seated oil seal keeps lubricant in and contaminants out around rotating shafts, directly affecting the service life of bearings and internal drive components.
- Fluid Containment Integrity — On trash pump applications, a failed seal can allow pump fluid or contaminants to migrate into the engine or gearbox — replacing this seal at the first sign of leakage prevents escalating damage.
An oil seal creates a dynamic barrier between a rotating shaft and a stationary housing, retaining lubricating oil or grease within the assembly while blocking dirt, water, and debris from entering. In trash pumps, this seal protects the impeller shaft and drive components from fluid contamination that would accelerate wear. In reversible plate compactors, it maintains lubrication integrity within the exciter or drive housing, where bearing failure caused by dry or contaminated grease can lead to costly internal damage. When this seal hardens, cracks, or loses its lip tension, leaks develop quickly — making timely replacement essential to protecting the surrounding components.
