The Multiquip 12698 is a genuine OEM O-Ring Size 2-151 Nitrile 70A designed for Whiteman and international ride-on power trowel models including HHN31V, HHN34TVD, HHXD5, HHXG5, HHXD5-ES, EHHNK5, HHXDF4-DF5, and HHNG5. As a direct Multiquip OEM component, part 12698 is manufactured to the exact material grade and dimensional specification required for a proper seal in these machines. Sourced directly through authorized channels, this nitrile 70A compound O-ring delivers the compression and chemical resistance needed to maintain hydraulic and fluid system integrity on your ride-on trowel. DHS Equipment stocks genuine Multiquip parts so you can get the right component without guesswork.
Key Features
- Nitrile 70A Material Grade — Shore A 70 hardness nitrile rubber provides the correct compression set and resistance to hydraulic fluids, oils, and grease found in ride-on trowel systems.
- Exact Size 2-151 Specification — Dimensionally matched to the Size 2-151 standard, this O-ring seats correctly in its groove without shimming or modification.
- Genuine OEM Part — Sourced directly from Multiquip, part 12698 meets the same material and dimensional standards as the original component installed at the factory.
- Broad Ride-On Trowel Fitment — Confirmed for HHN31V, HHN34TVD, HHXD5, HHXG5, HHXD5-ES, EHHNK5, HHXDF4-DF5, and HHNG5 Whiteman and international ride-on power trowel models.
- Fluid System Integrity — A correctly seated O-ring maintains consistent hydraulic pressure and prevents fluid leaks that can lead to blade pitch control issues or hydraulic system damage.
- Fuel and Fluid Compatibility — Nitrile compound construction resists degradation from petroleum-based hydraulic fluids and lubricants common in ride-on trowel drive and blade systems.
An O-ring is a precision sealing element that sits in a machined groove between two mating surfaces, forming a pressure-tight barrier against fluid or gas leakage. In ride-on power trowels, O-rings are used throughout hydraulic circuits, gearboxes, and fluid reservoirs where maintaining consistent pressure is critical to blade pitch control and machine drive performance. When an O-ring wears, hardens, or takes a permanent set, it loses its ability to seal — resulting in fluid leaks, pressure loss, and potential damage to surrounding hydraulic components if not addressed promptly.
