The Wacker Neuson Screw Plug is a genuine OEM component designed for MDP3, MDP3X, and PT3G-c series diaphragm and trash pumps. Sourced directly from Wacker Neuson, this screw plug meets the exact specifications of the original part, ensuring a correct, leak-free installation every time. It is also confirmed to fit MDP3-CN water pump configurations, making it a versatile service part across multiple pump lines in the Wacker Neuson lineup.
Key Features
- Genuine OEM Sealing Integrity — Manufactured to Wacker Neuson's exact thread form and material spec, so the plug seats and seals the same way as the original — no weeping, no remedial sealing compounds needed.
- Direct Drop-In Replacement — Matches the original thread pitch and head profile, so it threads straight into the pump housing without chasing threads or adapting fittings.
- Broad Pump Family Coverage — A single part number covers MDP3, MDP3X, MDP3-CN, PT3G-c CE, and PT3G-c CN pump models, simplifying parts inventory for fleets running multiple Wacker Neuson pumps.
- Maintains Pump Pressure and Fluid Containment — A failed or missing screw plug allows fluid loss and pressure bleed-off, degrading pump output and potentially exposing operators to discharge fluid. This OEM replacement restores proper containment immediately.
- Verified Part Number Fit — Part number 5100061607 is cross-referenced across five Wacker Neuson pump configurations, giving you confidence you are ordering the correct plug for your machine before it ships.
A screw plug is a threaded closure used to seal access or drain ports in a pump housing. It keeps fluid contained within the pump circuit and maintains the internal pressure necessary for consistent pump performance. When a screw plug is damaged, cross-threaded, or missing entirely, the pump loses fluid and pressure at the port, which can cause erratic flow output and introduce contaminants into the pump body — leading to accelerated wear on internal components.
