The Wacker Neuson is a genuine OEM Flapper Valve Gasket designed for PTS4V and PTK4 series self-priming centrifugal trash pumps. As a direct OEM replacement sourced through Wacker Neuson's authorized parts program, this gasket is manufactured to the same specifications as the original component installed at the factory. It fits the PTS4V, PTS4V(I), and PTK4(I) pump configurations, covering both standard and international variants of the 100mm/4-inch platform. If your pump is losing prime, showing reduced suction, or leaking at the flapper valve seat, replacing this gasket is a critical first step in restoring full performance.
Key Features
- OEM-Grade Sealing Material — Manufactured to Wacker Neuson's material specification for compression resistance and fluid compatibility, ensuring a consistent, leak-free seal at the flapper valve interface.
- Drop-In Replacement — Matches the original gasket profile exactly, seating directly against the flapper valve housing without trimming or reworking the mating surface.
- Fits PTS4V and PTK4 Series — Compatible with PTS4V, PTS4V(I), and PTK4(I) 100mm/4-inch centrifugal trash pumps across multiple production builds.
- Restores Priming Performance — A failed or compressed gasket allows air to bypass the flapper valve, causing the pump to lose prime and cavitate; a fresh gasket brings suction and flow rates back to spec.
- Genuine OEM Part — Carries the Wacker Neuson part number 5000030606 and is backed by the manufacturer's OEM parts assurance — the same component used in original pump assembly.
The flapper valve gasket creates an airtight seal between the flapper valve and its seat inside the pump's suction chamber. This seal is what allows the pump to build and hold prime — without it, air leaks past the valve and the pump cannot generate the suction needed to draw fluid. Over time, heat cycling, debris contact, and compression cause the gasket to harden, crack, or deform, which directly degrades priming ability and overall pump output. Replacing the gasket at the first sign of priming difficulty is one of the most straightforward ways to return a PTS4V or PTK4 pump to full working condition.
