The Multiquip 050300440 O-Ring S-44 is a genuine OEM seal designed for Multiquip rammer models MT-65H, MT-75H, MT-65HA, and MT75HS. Sourced directly from Multiquip, this O-ring delivers the exact material compound, durometer rating, and dimensional profile required for a proper seal in your rammer's fuel or fluid system. Confirm your model against the fitment list before ordering to ensure compatibility with your specific machine configuration.
Key Features
- OEM-Grade Elastomer Compound — Manufactured to Multiquip's original material specification, ensuring the correct compression set and chemical resistance for rammer operating conditions.
- Exact-Profile Seal — Matches the S-44 cross-section and inner diameter precisely, seating cleanly into the original groove without adjustment or trimming.
- Confirmed Rammer Fitment — Compatible with MT-65H, MT-75H, MT-65HA, and MT75HS Multiquip tamper models; verify your model code before ordering.
- Leak Prevention at the Source — A correctly seated O-ring maintains fluid containment under the vibration and thermal cycling that rammers produce; a worn or damaged seal allows seepage that can affect engine or fuel system performance.
- Genuine OEM Part — Supplied as a Multiquip genuine OEM component under part number 050300440, so you receive the same part installed at the factory.
An O-ring is a precision elastomeric seal that fits into a machined groove and creates a pressure-tight barrier between mating components. In a rammer, O-rings are used throughout the fuel system, carburetor, and internal assemblies to prevent fluid or air leaks that would otherwise cause hard starting, rough running, or fuel contamination. When an O-ring hardens, cracks, or becomes compressed over time, the seal fails and leaks develop — replacing it with the correct Multiquip 050300440 O-Ring S-44 restores the proper barrier and keeps the machine running as intended.
