The Multiquip M805835 Gasket 4020Eab Sth55Hp is a genuine OEM component designed for the STX55J6 and STX55Y6 hydrostatic ride-on power trowels. As a direct OEM replacement, it is manufactured to the exact material and dimensional standards required for proper sealing performance in these machines. DHS Equipment sources this part directly through authorized Multiquip channels, so you can order with confidence knowing you are receiving the correct part for your equipment. Confirm your model against the STX55J6 and STX55Y6 fitment before ordering to ensure a correct application.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the exact material grade and compression profile specified for the 4020Eab Sth55Hp application, ensuring a proper seal without leakage.
- Drop-In Fitment for STX55 Series — Engineered specifically for the STX55J6 and STX55Y6 hydrostatic ride-on trowels, matching the original mounting surfaces and bolt pattern.
- Prevents Fluid or Air Bypass — A correctly seated gasket maintains the pressure and fluid boundaries within the assembly, preventing contamination, loss of hydraulic efficiency, or engine performance issues.
- OEM-Sourced Replacement — Supplied as a genuine Multiquip part, not a generic substitute, so material composition and thickness match what the machine was built with.
- Supports Proper Machine Operation — A failed or deteriorated gasket can cause fluid leaks, overheating, or loss of hydraulic pressure in the trowel's drive system — replacing it promptly keeps the machine performing as intended.
A gasket creates a static seal between two mating surfaces within an engine or hydraulic assembly, preventing fluids, gases, or pressure from escaping the joint. In a ride-on power trowel like the STX55 series, maintaining these seals is critical to the integrity of the engine and hydraulic systems that control blade pitch and machine drive. When a gasket wears out, warps, or fails, it can allow fluid leaks or pressure loss that directly degrades trowel performance and can lead to more extensive internal damage if left unaddressed.
