The Multiquip 50411900 is a genuine OEM Closing Plug 7 designed for a range of Multiquip equipment including MVH502DSB2 and MVH502DSB reversible plate compactors, the MDR-9D power trowel, and the MQ41TDH trash pump. As a direct OEM replacement, this plug is manufactured to the exact material and dimensional standards required by the original design, ensuring a secure, leak-free seal every time. Sourced directly through Multiquip's authorized parts network, the 50411900 gives you confidence that you're installing the correct component for your specific machine. Cross-reference your model code before ordering to confirm compatibility.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Multiquip's original material and thread specifications, ensuring the plug seats and seals correctly without weeping or working loose under vibration.
- Direct Drop-In Installation — Matches the original port geometry on compatible Multiquip equipment, threading in cleanly without the need for adaptation or rework.
- Broad Multiquip Fitment — Compatible with MVH502DSB2, MVH502DSB, MDR-9D, and MQ41TDH machines, covering reversible plate compactors, a power trowel, and a trash pump application.
- Fluid and Pressure Retention — A correctly seated closing plug prevents fluid loss, contamination ingress, and pressure drop in the circuit it serves, keeping the host system functioning within its designed operating range.
- Fluid System Safety — Worn or missing closing plugs in hydraulic, fuel, or fluid passages can result in leaks that create fire risk or environmental hazard; replacing with the correct OEM plug restores safe, compliant operation.
A closing plug is a threaded or press-fit sealing component used to cap off a port, passage, or bore in a machine's housing, manifold, or fluid circuit. It prevents fluid — whether hydraulic oil, lubricant, or fuel — from escaping an unused or service-access port, and blocks contaminants from entering the system. When a closing plug is damaged, stripped, or missing entirely, the machine can suffer fluid loss, loss of pressure, or internal contamination that leads to accelerated wear or component failure in the surrounding circuit.
