The Multiquip 16185 Plug Fitting 1/4MP Square Head is a genuine OEM component designed for a wide range of Multiquip and Whiteman equipment including ride-on power trowels, plate compactors, vibratory screeds, rollers, and light towers. As a direct OEM replacement, part 16185 is manufactured to the same specifications as the original, ensuring a correct fit across compatible models such as the MD105, STXDF, HHNG5, MVH158GH, MRH800GS, LT6K, and HHN31V. Sourcing a genuine Multiquip fitting means you avoid the guesswork that comes with non-spec alternatives and keep hydraulic or fluid systems properly sealed. DHS Equipment stocks this part to help you get your equipment back in service with confidence.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original thread and seating specifications for a leak-free, pressure-rated connection in hydraulic and fluid port applications.
- 1/4MP Square Head Drive — The square head profile allows standard tooling to seat and torque the fitting securely, eliminating slippage during installation.
- Broad Equipment Compatibility — Fits MD105, STXDF, HHNG5, HHN31V, JWN24HTCSL/HSCSL, EHHNK5, MVH158GH, MRH800GS, LT6K, LT6KV, and WSHE-A Series equipment.
- Fluid System Integrity — A correctly installed plug fitting maintains system pressure and prevents contamination ingress at open ports, protecting downstream hydraulic and fluid components.
- Hydraulic System Safety — Improperly plugged or leaking ports in hydraulic circuits can cause pressure loss and uncontrolled component behavior; using the correct OEM fitting keeps the system operating within design limits.
A plug fitting is used to seal off an unused or temporarily open fluid port in a hydraulic or lubrication circuit. The 1/4MP thread designation indicates a male pipe thread at a quarter-inch nominal size, and the square head allows a wrench to apply the correct torque without damaging the fitting body. When a plug fitting fails, cracks, or is missing entirely, the open port can allow hydraulic fluid to leak out or contaminants such as dirt and moisture to enter the system — both conditions accelerate wear on pumps, valves, and actuators downstream.
