The Wacker Neuson 5200020306 is a genuine OEM Gasket Set designed for APT4S and APT4T series pumps. Sourced directly from Wacker Neuson, this gasket set delivers the exact material grade, thickness, and sealing profile specified for these pump models — including standard and cold weather variants. It fits the APT4S Pump with Skid, APT4T Pump with Surge Brake, APT4T Pump with Electric Brake, and their corresponding cold weather configurations. When a gasket fails, fluid leaks and pressure loss follow quickly, so replacing the 5200020306 with a genuine OEM part restores proper sealing and keeps the pump operating at spec.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's material and compression specifications, ensuring proper fluid containment and pressure retention across the APT4S and APT4T pump families.
- Complete Set for Full Service Coverage — Includes all gaskets required for the service interval, so you have every sealing surface covered in a single part number.
- Broad APT4S and APT4T Fitment — Confirmed fit across APT4S Pump with Skid, APT4T Pump with Surge Brake, APT4T Pump with Electric Brake, and all corresponding cold weather variants.
- Prevents Fluid Loss and Pressure Drop — A worn or compromised gasket allows fluid to bypass sealing surfaces, reducing pump output and risking damage to internal components. Replacing with this set restores full sealing integrity.
- Fuel and Fluid System Safety — Proper gasket sealing is critical in pump applications where leaking fluids can create hazardous conditions. Using the correct OEM set helps maintain safe, compliant operation.
A gasket set provides the sealing layers between mating surfaces inside the pump assembly — preventing fluids from escaping past joints, covers, and internal passages under operating pressure. When gaskets degrade, crack, or compress unevenly over time, leaks develop that reduce pump efficiency and can lead to internal contamination or component damage. Replacing the full gasket set during service ensures every sealing surface is restored at once, avoiding the partial fixes that leave older gaskets in place alongside new ones.
