Multiquip 050710080 O-Ring FJ-1816

The Multiquip O-Ring FJ-1816 is a genuine OEM seal designed for MTX70HF, MTX70HDR, MTX80HDR, and MTX70HD rammers, as well as the MVH128GH plate compactor. As a factory-sourced component, meets the exact material and dimensional specifications required for proper sealing in the original equipment. DHS Equipment supplies this part direct, so you can be confident you are getting the correct O-Ring FJ-1816 for your machine without guesswork.

Key Features

• Genuine OEM Sealing Material — Manufactured to the exact compound and durometer specification required for this application, ensuring consistent compression and sealing performance across operating temperatures.
• Direct-Fit Installation — Dimensioned to seat precisely in the original groove without trimming or adjustment, allowing a straightforward swap during service.
• Broad Rammer and Compactor Coverage — Confirmed fitment for MTX70HF, MTX70HDR, MTX80HDR, and MTX70HD rammers, plus the MVH128GH reversible plate compactor.
• Leak Prevention — A correctly seated O-Ring FJ-1816 maintains fluid or air containment within the assembly; a worn or flattened ring leads to seepage, pressure loss, and accelerated wear on surrounding components.
• Fuel and Fluid System Integrity — Used within fuel or hydraulic passages, this seal helps prevent contamination ingress and fluid loss, both of which can cause hard-starting, erratic operation, or component damage.

An O-ring is a circular elastomeric seal that sits in a machined groove between two mating surfaces or around a shaft or port. Its job is to block the passage of fluids or gases by deforming slightly under compression when the assembly is torqued together. Over time, heat cycling, fuel exposure, and mechanical stress cause the material to harden, flatten, or crack, breaking that seal. When an O-ring fails, the result is a leak or pressure loss that can compromise fuel delivery, lubrication, or hydraulic function — making timely replacement essential to keeping the machine running correctly.
