The Wacker Neuson 5200020099 Gasket is a genuine OEM component designed for APT4T and APT4S series pumps. As a direct factory replacement, this gasket ensures a proper seal across the full range of APT4T and APT4S configurations, including electric brake, surge brake, skid-mounted, and cold weather variants. Sourced directly from Wacker Neuson, part number 5200020099 carries the same material and dimensional specifications as the part originally installed at the factory.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's original material specification, ensuring correct compression and sealing performance at pump mating surfaces.
- Drop-In Replacement — Matches original mounting geometry and surface profile, allowing straightforward installation without rework or trimming.
- Broad APT4 Series Coverage — Compatible with APT4T (Electric Brake and Surge Brake) and APT4S (Skid-mounted) models, including all corresponding Cold Weather variants.
- Leak Prevention — A correctly seated gasket maintains fluid containment and pressure integrity within the pump assembly; a worn or damaged gasket can lead to fluid loss and reduced pump output.
- Genuine OEM Confidence — Backed by Wacker Neuson's parts program, so you know the part number, fit, and material grade are exactly what the machine was built around.
A gasket forms a static seal between two mating surfaces in the pump assembly, preventing fluid or pressure from escaping at the joint. In a centrifugal pump like the APT4 series, maintaining that seal is critical to consistent output and efficient operation. When a gasket degrades, cracks, or is compressed beyond its service life, leaks develop at the joint — reducing system pressure, introducing contamination risk, and forcing more frequent fluid top-ups. Replacing a worn gasket promptly with the correct OEM part restores the original sealed condition and protects the surrounding components from collateral damage.
