The Multiquip 12125239450 Oil Pressure Sender is a genuine OEM component designed for a range of Multiquip ride-on trowels, heavy-duty reversible plate compactors, and walk-behind rollers, including the MDR-9DYE, MVH-200DA2, MVH-304DSB, MVH-306DS2, MVH-402DSB, MVH-406DSY, MRH-800DS, and MRH800DS2. Sourced directly from Multiquip, this sender matches the original unit fitted at the factory for a straight-swap installation with no guesswork. It is the correct part to use when restoring accurate oil pressure monitoring to your equipment after sender failure or routine service. DHS Equipment stocks genuine Multiquip OEM parts so you can get your machine back to work with confidence.
Key Features
- Genuine OEM Electrical Spec — Calibrated to the correct resistance range and output signal for Multiquip engine monitoring systems, ensuring accurate gauge readings rather than false warnings or missed alerts.
- Direct-Swap Installation — Matches the original thread pitch, connector type, and body dimensions of the sender it replaces, dropping straight into the existing port without adapters or modification.
- Broad Multiquip Fitment — Compatible with MDR-9DYE ride-on trowels, MVH-200DA2, MVH-304DSB, MVH-306DS2, MVH-402DSB, and MVH-406DSY plate compactors, and MRH-800DS and MRH800DS2 walk-behind rollers.
- Protects Engine from Low-Oil Events — A correctly functioning sender keeps the oil pressure warning circuit live, allowing the operator to catch dangerous pressure drops before engine damage occurs.
- Safety-Critical Monitoring — On diesel-powered compaction and troweling equipment, reliable oil pressure signaling is essential for operator awareness and machine protection during high-load operation.
The oil pressure sender is a small threaded sensor mounted directly on the engine block that monitors the lubrication system's operating pressure and transmits a corresponding signal to the instrument panel or warning light circuit. When oil pressure drops below a safe threshold — due to low oil level, pump wear, or a developing internal fault — the sender triggers an alert so the operator can shut the machine down before serious engine damage occurs. A failed or faulty sender can result in either a permanently illuminated warning light that masks real conditions or, more dangerously, no warning at all when pressure actually falls, leaving the engine vulnerable to rapid wear or seizure.
