The Wacker Neuson 5100036375 is a genuine OEM Outlet Valve designed for APT4S and APT4T series pumps. As a direct factory replacement, this valve is built to the same specifications as the original component installed at the time of manufacture, ensuring consistent pump performance across the full range of APT4S and APT4T configurations — including standard, Cold Weather, Surge Brake, and Electric Brake variants. Whether you are servicing an APT4S Pump with Skid or an APT4T Pump with Electric Brake, part number 5100036375 is the correct OEM replacement. Stocking genuine Wacker Neuson parts means your pump is back in service faster, with no guesswork on fitment or function.
Key Features
- Genuine OEM Valve Construction — Manufactured to Wacker Neuson's original flow and sealing specifications, ensuring the valve opens and closes at the correct pressure thresholds for accurate pump output.
- Direct-Swap Installation — Matches the original outlet port geometry and connection interface of the APT4S and APT4T pump housings for a straightforward, tool-matched replacement.
- Broad APT Series Compatibility — Confirmed fitment across APT4S Pump with Skid, APT4S Cold Weather, APT4T Surge Brake, APT4T Electric Brake, and their Cold Weather counterparts.
- Maintains Consistent Flow Direction — A correctly functioning outlet valve prevents backflow and maintains discharge pressure, keeping pump output steady and predictable under load.
- Fuel and Fluid Integrity — As part of the pump's fluid path, a worn or failed outlet valve can cause backflow, pressure loss, or fluid contamination — replacing it promptly protects downstream connections and system integrity.
The outlet valve controls the direction of fluid flow through the pump's discharge side, allowing liquid to exit the pump while preventing it from flowing backward when the pump cycle reverses or stops. It works in coordination with the inlet valve to create the pressure differential that drives fluid through the system efficiently. When the outlet valve wears, sticks, or fails to seat properly, the pump loses discharge pressure, output becomes erratic, and backflow can damage other pump components or connected equipment.
