The Multiquip EM151 is a genuine OEM Seal designed for a wide range of Multiquip and Whiteman equipment, including STX55, HTX44, MD80, MD105, LD60, MTX70, MTX80HDR, WBH-16E, WBH-16F, and many additional models across the Multiquip portfolio. As a factory-sourced component, the EM151 meets the exact specifications required by the original equipment, ensuring a correct, consistent fit across every compatible application. This seal is stocked and sold by DHS Equipment to help you get the right part the first time and keep your equipment running at full capacity.

Key Features

• Genuine OEM Material Grade — Factory-sourced seal compound matched to the original compression and temperature tolerances required across Multiquip's hydrostatic, mechanical, and engine-driven equipment lines.
• Broad Cross-Equipment Compatibility — A single part number covering ride-on trowels (STX55, HTX44, HTX6H, STX6H, MD80, MD105, LD60), power buggies (WBH-16E, WBH-16F), rammers (MTX50HD through MTX80HDR), rollers, vibrators, pumps, saws, and screeds.
• Drop-In Replacement — Dimensionally identical to the original seal, allowing direct installation without machining or modification to housings, shafts, or mating surfaces.
• Leak Prevention Across High-Cycle Applications — A properly seated seal maintains fluid containment in hydraulic, fuel, and lubrication systems; a worn or failed seal leads to fluid loss, contamination of adjacent components, and accelerated wear.
• Verified Part Number Integrity — Sourced and cataloged as EM151, ensuring the part you receive matches the engineering drawing referenced in Multiquip service documentation for each compatible model.

A seal is a precision component designed to prevent the passage of fluid, air, or contaminants past a moving or static interface — such as a rotating shaft, hydraulic cylinder, or fuel system connection. In equipment like ride-on trowels, rammers, and hydraulic buggies, seals are critical to maintaining system pressure, protecting bearings and internal components from contamination, and preventing fluid leaks that can lead to performance loss or environmental hazards. When a seal deteriorates or fails, symptoms typically include visible leaks, loss of hydraulic pressure, increased wear on surrounding components, and potential damage to the machine if left uncorrected.
