The Wacker Neuson 5000119409 is a genuine OEM O-Ring designed for the PT3 series 75mm/3-inch self-priming centrifugal trash pumps, including PT3, PT3A, PT3H, and PT3V variants. As a genuine Wacker Neuson part, the part is manufactured to the exact material and dimensional specifications required for proper sealing performance in these pumps. This O-Ring is a direct-fit replacement, verified across multiple machine numbers within the PT3 family. Keep a spare on hand — O-Rings are a routine service item on any pump that sees regular use.
Key Features
- Drop-In Replacement — Dimensionally matched to the original seating groove; seats correctly without trimming, stretching, or shimming.
- Broad PT3 Family Coverage — Confirmed fitment across PT3, PT3A, PT3H, and PT3V 75mm/3-inch centrifugal trash pump configurations.
- Leak-Free Sealing — A correctly seated O-Ring maintains pump prime and system pressure; a failed or degraded O-Ring causes air ingestion, prime loss, and reduced flow output.
- Genuine Wacker Neuson Part — Sourced directly from Wacker Neuson, carrying the same part number 5000119409 used by authorized service centers.
An O-Ring creates a pressure-tight seal between mating pump components, preventing air from entering the fluid path and stopping liquid from escaping at joints or covers. In a self-priming trash pump like the PT3 series, a sound O-Ring is critical to the pump's ability to draw fluid and maintain consistent output pressure. When an O-Ring degrades — through heat cycling, chemical exposure, or mechanical wear — the pump loses prime, flow drops off, and the machine may fail to move fluid altogether.
