The Wacker Neuson 5000119408 is a genuine OEM O-Ring designed for the PT3 series 75mm/3-inch self-priming centrifugal trash pumps. Sourced directly from Wacker Neuson, this O-Ring meets the exact material and dimensional specifications of the original part installed at the factory. It is confirmed compatible across the PT3, PT3A, PT3H, and PT3V model variants, making it a dependable choice for scheduled maintenance or seal replacement. Verifying your machine number against the fitment list before ordering ensures a correct, confident replacement.
Key Features
- Correct Seal Material and Geometry — As a genuine OEM component, this O-Ring matches the original compound grade and cross-sectional dimensions required to maintain a proper fluid seal in Wacker Neuson PT3 series pump housings.
- Drop-In Replacement — Engineered to seat into the same groove and mating surface as the original, allowing straightforward installation without modification to the pump assembly.
- Broad PT3 Series Coverage — Fits PT3, PT3A, PT3H, and PT3V model variants across multiple machine configurations, consolidating compatibility within the 75mm/3-inch trash pump family.
- Leak Prevention at the Source — A correctly seated O-Ring maintains pump prime and prevents fluid bypass between mating pump surfaces, directly supporting suction performance and flow rate.
- OEM Part Number 5000119408 — Cross-reference this number against your parts manual or machine serial tag to confirm fitment before ordering.
An O-Ring is a looped elastomeric seal that sits in a machined groove between two mating surfaces — in a trash pump, this is typically found at housing joints, port connections, or impeller covers. Its job is to prevent water, slurry, or air from bypassing the sealed interface, which is critical for maintaining pump prime and consistent discharge pressure. When an O-Ring becomes cracked, compressed flat, or chemically degraded, the pump may lose prime, draw air, or leak fluid at the joint — reducing output and putting the pump at risk of running dry.
