Multiquip 12979549551 Non-Asbestos Gasket 3Tne88

The Multiquip 12979549551 is a genuine OEM Non-Asbestos Gasket 3Tne88 designed for Whiteman hydrostatic ride-on power trowels, including the STXD6i, HTXD6i, and STX55Y6. As a factory-sourced component, it meets the exact material and dimensional standards required by the original engine assembly. Sourced directly through Multiquip's authorized parts network, 12979549551 ensures a correct, confident fit with no guesswork on compatibility. If you're servicing any of these trowel models, this is the right gasket for the job.

Key Features

• Asbestos-Free Material Construction — Engineered with non-asbestos composite materials that deliver proper sealing compression and thermal resistance for the 3Tne88 engine environment.
• Direct OEM Replacement — Manufactured to the exact profile and thickness of the original gasket, seating correctly against mating surfaces without trimming or shimming.
• Confirmed Fitment for Key Trowel Models — Verified for use on STXD6i, HTXD6i, and STX55Y6 Whiteman hydrostatic ride-on power trowels.
• Maintains Engine Sealing Integrity — A properly seated gasket prevents combustion gas leakage and coolant or oil intrusion at mating surfaces, keeping engine compression and output consistent.
• Genuine Multiquip OEM Part — Backed by Multiquip's authorized parts program, ensuring you receive the correct specification component every time you order part number 12979549551.

A gasket forms a pressure-tight seal between two mating engine surfaces, preventing combustion gases, oil, or coolant from escaping at the joint. In the 3Tne88 engine used in these Whiteman ride-on trowels, maintaining that seal is critical to sustaining proper compression and preventing contamination between engine systems. When a gasket deteriorates or fails, the result is typically lost compression, fluid leaks, or engine overheating — all of which bring the trowel to a stop and risk wider engine damage if left unaddressed.
