The Multiquip 12915049811 is a genuine OEM Non-Asbestos Gasket 3Tne88 designed for Multiquip hydrostatic ride-on power trowels, including the STX55J6, STXD6i, HTXD6i, and STX55Y6. As a direct Multiquip OEM component, part 12915049811 is manufactured to the exact material and dimensional specifications required by the 3Tne88 engine fitted to these machines. Verified fitment across the STX and HTX series means you can order with confidence and get the trowel back to work without guesswork.
Key Features
- Asbestos-Free Sealing Material — Engineered with a non-asbestos compound that delivers the compression and heat resistance required for the 3Tne88 engine's sealing surfaces.
- Genuine OEM Component — Sourced directly from Multiquip, this gasket matches the exact thickness, port geometry, and material grade specified for the original engine build.
- Confirmed Fitment for STX and HTX Series — Verified for STX55J6, STXD6i, HTXD6i, and STX55Y6 hydrostatic ride-on trowels — no guesswork when ordering by part number 12915049811.
- Maintains Proper Compression and Sealing — A correctly seated gasket prevents combustion gas leakage and coolant or oil intrusion, protecting engine integrity during high-cycle troweling operations.
- Drop-In Installation — Designed to seat against the original mating surfaces of the 3Tne88 engine without rework or shimming, supporting straightforward engine service.
A gasket seals the mating surfaces between two engine components — such as the cylinder head, block, or manifold — preventing the escape of combustion gases, coolant, or oil under operating pressure and temperature. In the 3Tne88 diesel engine used in Multiquip's hydrostatic ride-on trowels, maintaining an intact seal is critical to sustaining compression and preventing cross-contamination between fluid systems. When a gasket degrades, cracks, or blows, it can cause loss of power, overheating, or internal engine damage — making timely replacement with the correct OEM part essential to keeping the machine performing at full capacity.
