The Multiquip 050100900 O-Ring is a genuine OEM replacement designed for MTX70HD, MTX70HF, MTX70HDR, and MTX80HDR rammers. Sourced directly from Multiquip, this O-Ring delivers the exact material composition, dimensional tolerancing, and compression characteristics required to maintain a proper seal in your machine. It is a direct-fit replacement for the MT-75H application, confirming compatibility across the MTX70 and MTX80 rammer series. When seal integrity matters on the jobsite, using the correct OEM part is the reliable choice.
Key Features
- Precise OEM Seal Geometry — Manufactured to exact dimensional and durometer specifications, ensuring consistent compression and sealing performance in rammer applications.
- Direct-Fit Replacement — Drops into the same seat as the original with no trimming or adaptation needed, maintaining correct compression at every contact point.
- Broad Rammer Fitment — Compatible with MTX70HD, MTX70HF, MTX70HDR, and MTX80HDR Multiquip tamper models, covering both GX100 and GX120 Honda engine variants.
- Leak Prevention — A correctly seated O-Ring keeps fuel, oil, or fluid contained within the circuit; a degraded or incorrect O-Ring leads to seepage, contamination, and accelerated component wear.
- Genuine Multiquip OEM Part — Supplied by an authorized Multiquip dealer, this component meets the same material and performance standards as the part originally installed at the factory.
An O-Ring is a circular elastomeric seal used throughout engine and fuel system assemblies to prevent fluid or gas from escaping at joints, fittings, and housing interfaces. In a rammer like the MTX70 or MTX80 series, O-Rings are critical at points where fuel delivery, lubrication, or air circuits must remain fully sealed to sustain proper engine operation. When an O-Ring hardens, cracks, or takes a permanent set, the resulting leak can cause rough running, fuel contamination, or oil loss — making timely replacement with a correctly specified part essential to keeping the machine performing as intended.
