The Multiquip 12700 Case O-Ring Seal is a genuine OEM replacement seal designed for Whiteman and international ride-on power trowel models including HHN34TVD, HHXDF4-DF5, HHXD5, HHXD5-ES, HHXG5, HHNG5, HHN31V, and EHHNK5. As a direct OEM component sourced through Multiquip's authorized parts network, 12700 meets the exact material and dimensional specification of the original seal installed at the factory. Correct sealing is critical on ride-on trowel gearboxes and housings, and using the right replacement keeps fluid where it belongs and contaminants out. DHS Equipment stocks this part to help you get your machine back to work without unnecessary delays.
Key Features
- Genuine OEM Sealing Material — Produced to the same elastomer compound and compression profile as the original, ensuring a consistent, leak-free interface at the case joint.
- Exact Dimensional Spec — Measures 0.103 x 46.38, matching the original groove geometry for a drop-in installation without modification to the housing.
- Broad Ride-On Trowel Coverage — Fits HHN34TVD, HHXDF4-DF5, HHXD5, HHXD5-ES, HHXG5, HHNG5, HHN31V, and EHHNK5 Whiteman and international series ride-on power trowels.
- Protects Internal Components — A properly seated case O-ring prevents gearbox oil or hydraulic fluid leaks that can lead to premature wear of bearings, shafts, and gears inside the trowel drive housing.
- Fluid Containment and Contamination Control — Keeps external debris, water, and jobsite grit from entering the case, which is especially important on concrete finishing equipment operating in abrasive environments.
A case O-ring seal forms the static sealing barrier between mating halves of a gearbox or drive housing on a ride-on power trowel. It prevents internal lubricants from escaping the case and blocks outside contaminants from entering and damaging precision internal components. When this seal ages, hardens, or becomes compressed, it loses its ability to conform to the mating surfaces — resulting in visible fluid leaks, dropping oil levels, and potential damage to the gears and bearings it was protecting. Replacing a worn case O-ring promptly is one of the lowest-cost, highest-impact maintenance steps on a ride-on trowel.
