The Wacker Neuson 5100040906 is a genuine OEM Elbow Fitting designed for the APT4T and APT4S self-priming pump series. Sourced directly through the Wacker Neuson parts network, this fitting is manufactured to the same specifications as the original component installed at the factory. Fitment covers the full APT4T and APT4S lineup, including Surge Brake, Electric Brake, and Cold Weather variants, as well as the APT4S Pump with Skid configurations. When a fitting fails or leaks, fluid routing is compromised — having the correct OEM replacement on hand gets your pump back to full operation without guesswork.
Key Features
- OEM-Matched Geometry — Manufactured to the exact angle, thread pitch, and port sizing of the original fitting, ensuring a leak-free connection at installation.
- Direct Replacement — Installs in the same position as the factory fitting with no additional adapters or modifications to existing lines or ports.
- Broad APT4T and APT4S Compatibility — Fits Surge Brake, Electric Brake, and Cold Weather variants of the APT4T, plus standard and Skid-mounted APT4S pump configurations.
- Maintains Fluid Circuit Integrity — A correctly seated elbow fitting keeps pump fluid routed under designed pressure, preventing pressure loss, fluid contamination, and wet-end performance degradation.
- Genuine Wacker Neuson OEM Part — Backed by Wacker Neuson's parts program, part number 5100040906 confirms an exact match to the original specification for your pump model.
An elbow fitting is a directional connector used within the fluid circuit of a pump system to change the routing angle of a hose or line without introducing stress or flow restriction at the junction. On the APT4T and APT4S pump series, these fittings maintain the integrity of fluid pathways critical to priming performance and consistent output. When an elbow fitting cracks, strips, or develops a seal failure, the result is fluid leakage, loss of prime, or air ingestion into the system — all of which degrade pump output and can lead to accelerated wear on internal wet-end components.
