The Wacker Neuson 5100018119 is a genuine OEM Tee Fitting designed for the APT4, APT6, and APT8 series self-priming pumps, covering skid-mounted, surge brake, electric brake, and cold weather configurations. As a factory-sourced component, it meets the exact dimensional and material specifications of the original part installed at the factory. This fitting is compatible across a wide range of APT pump variants including APT4T, APT4S, APT6T, APT6S, APT8T, and APT8S models, making it a go-to replacement for operators managing multiple pump sizes in their fleet. Verify your model and machine number before ordering to confirm the correct application.
Key Features
- Genuine OEM Construction — Manufactured to Wacker Neuson's original material and dimensional specifications, ensuring proper thread engagement and leak-free sealing at the fitting junction.
- Drop-In Installation — Designed to match the original port sizing and thread pattern exactly, allowing direct installation into the existing fluid circuit without modification to adjacent lines or fittings.
- Broad APT Series Compatibility — Fits APT4, APT6, and APT8 pump families across skid, surge brake, electric brake, and cold weather variants — standard and CW configurations included.
- Maintains Fluid Circuit Integrity — A correctly seated tee fitting keeps pump flow properly directed and sealed; a failing or incorrect fitting can cause pressure loss, fluid leaks, or misdirected flow that degrades pump output.
- Fuel and Fluid System Reliability — Used within the pump's fluid routing system, this fitting plays a direct role in maintaining safe, contained flow paths — critical for pump operation in demanding jobsite environments.
A tee fitting is a three-port connector used to split or combine fluid flow within a pump's plumbing circuit. It allows a single inlet line to feed two outlets, or two return lines to merge into one, depending on how the circuit is configured. When a tee fitting cracks, strips, or develops a leak at any of its three ports, it can compromise the pump's prime, reduce discharge pressure, or cause fluid to escape the system — leading to reduced performance and potential damage to connected components.
