Wacker Neuson 5100000390 Gasket — Genuine OEM Replacement

The Wacker Neuson 5100000390 is a genuine OEM Gasket designed for a wide range of Wacker Neuson equipment, including CT36 and CT48 walk-behind concrete trowels, PT3A centrifugal trash pumps, BFS floor saws, GP and GV portable generators, BPU reversible vibratory plate compactors, and BPS single-direction vibratory plate compactors. As a direct genuine OEM component, this gasket is produced to the same specifications as the original part installed at the factory, ensuring an accurate fit without rework or adaptation. The 5100000390 covers an extensive range of models — confirm your machine's model number against the fitment list before ordering to ensure compatibility. Keeping a genuine replacement Gasket on hand means scheduled maintenance and unplanned seal failures can be addressed quickly, getting equipment back into service.

Key Features

• Genuine OEM Sealing Integrity — Manufactured to the same material grade and compression specification as the original, ensuring consistent sealing performance across all listed machine types.
• Broad Multi-Family Fitment — Compatible with CT36 and CT48 walk-behind concrete trowels, PT3A trash pumps, BFS940 and BFS914 floor saws, GP3800 and GV-series portable generators, and BPU/BPS vibratory plate compactors.
• Drop-In Replacement — Matches the original gasket profile exactly, seating correctly against mating surfaces without trimming, shimming, or re-torquing beyond standard spec.
• Leak Prevention Matters — A correctly seated gasket prevents fluid, fuel, or exhaust bypass between mating surfaces; a deteriorated or blown gasket leads to leaks, contamination, and potential engine damage if left unaddressed.
• Fuel and Fluid System Safety — On fuel system applications such as carburetor and pump assemblies, a compromised gasket can result in fuel leaks and fire risk; using a verified OEM replacement maintains the integrity of the sealed joint.

A gasket forms a static seal between two mating surfaces — such as a carburetor body and an intake, a pump housing and a cover, or an engine block and a peripheral component — preventing fluids, fuel, or gases from bypassing the joint under pressure. When a gasket hardens, cracks, or is compressed beyond recovery, the seal fails, allowing leaks that reduce performance and can cause secondary damage to surrounding components. Replacing a worn gasket with a genuine OEM part restores the original sealed interface and protects the machine from the cascade of problems that even a minor leak can trigger over time.
