The Wacker Neuson 5200020122 Gasket is a genuine OEM component designed for LTN4Y and LTN5Y series light towers and APT4T and APT4S series pump units. As a direct OEM replacement, it is manufactured to the same specifications as the original part, ensuring a proper seal wherever it is installed in these machines. This gasket covers an extensive range of LTN-series configurations — including standard, cold-weather, 60Hz, 120V/60Hz, and regional variants — as well as APT4T electric brake, surge brake, and APT4S skid-mount pump configurations. Keeping an accurate part number on hand is critical, and 5200020122 is the confirmed OEM reference for all compatible units listed.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to the original compression and material specification, so the gasket seats correctly and maintains a leak-free interface from the first installation.
- Drop-In Replacement — Matches the original gasket profile exactly, fitting the mating surfaces of compatible LTN and APT series assemblies without trimming or modification.
- Broad Fitment Coverage — Confirmed for the full LTN4Y and LTN5Y light tower families across multiple regional and electrical configurations, plus APT4T and APT4S pump units including cold-weather variants.
- Leak Prevention — A correctly installed gasket maintains critical fluid or combustion containment; a worn or damaged gasket can cause leaks that compromise machine operation and lead to more extensive repairs.
- Fuel and Fluid System Safety — Proper gasket integrity is essential in fuel and fluid pathways; using an OEM-spec replacement helps ensure the sealed joint meets the original design intent for safe, contained operation.
A gasket is a precision sealing component placed between two mating surfaces to prevent the passage of fluids, gases, or combustion pressure from the joint. In equipment like light towers and pump units, gaskets appear throughout the engine, fuel system, and fluid circuits, where even minor sealing failures can cause leaks, pressure loss, or contamination. When a gasket deteriorates — through heat cycling, compression set, or age — it can allow fluid to escape or outside contaminants to enter, which can quickly escalate into broader mechanical damage if not addressed with a correctly specified replacement.
