As a factory-sourced component, this part meets the original engineering specifications for the pump it serves, ensuring a proper seal and correct thread engagement every time. It fits the full APT4S and APT4T lineup, covering skid-mounted and trailer-mounted variants across both standard and cold-weather builds. When you need a straightforward, trustworthy replacement, the 5200020097 is the correct part for the job.
Key Features
- Genuine OEM Sealing Integrity — Sourced directly from Wacker Neuson, this drain plug is manufactured to the exact thread pitch and material spec required to maintain a leak-free seal in the pump housing.
- Direct Installation Fit — Threads in exactly as the original, with no reworking of the port or use of adapter fittings required.
- Broad APT4S and APT4T Compatibility — Confirmed fitment across APT4S Pump with Skid, APT4T Pump with Surge Brake, APT4T Pump with Electric Brake, and all corresponding cold-weather variants.
- Leak Prevention at the Drain Point — A worn or cross-threaded drain plug allows fluid loss and can introduce contaminants into the pump housing; a correctly seated replacement keeps the system properly sealed during operation and storage.
- Correct Part for Cold-Weather Configurations — Verified for use on cold-weather-spec APT4S and APT4T machines, where fluid management at the drain port is especially critical during winterization and seasonal service.
A drain plug seals the drain port on the pump housing or fluid reservoir, preventing coolant, oil, or pump fluid from escaping during normal operation. It is typically removed during scheduled maintenance or seasonal winterization to allow full drainage of the system. A drain plug that leaks, strips, or fails to seat correctly can lead to fluid loss, contamination, or pump damage — making a properly fitting, correctly threaded replacement essential for maintaining the pump between service intervals.
