The Wacker Neuson O-Ring is a genuine OEM sealing component designed for the PT3, PT3A, PT3H, and PT3V series 75mm/3-inch self-priming centrifugal trash pumps, as well as the BPS1550 and BPS2050 vibratory plate compactors. As a direct Wacker Neuson OEM part, the is manufactured to the exact material and dimensional tolerances required for proper sealing performance in your machine. Correct fitment is critical with O-rings — an off-spec ring that is even slightly undersized or made from the wrong elastomer compound will fail to seat properly, leading to fluid leaks and loss of prime in pump applications. Keeping the right seal in place ensures your equipment maintains full operating pressure and performs as intended on the job.
Key Features
- OEM Elastomer Specification — Manufactured from the exact compound and durometer grade specified by Wacker Neuson, ensuring correct compression set and chemical resistance for pump and compactor operating environments.
- Drop-In Sealing Fit — Dimensioned to seat precisely in the OEM groove without stretching, pinching, or trimming — critical for maintaining a leak-free seal at operating pressure.
- Broad PT3 Series Compatibility — Confirmed fitment across PT3, PT3A, PT3H, and PT3V trash pump variants, as well as BPS1550 and BPS2050 vibratory plate compactors.
- Leak Prevention at the Source — A properly seated O-ring maintains prime and fluid containment in trash pump assemblies; a worn or cracked ring causes loss of suction, fluid bypass, and pump failure.
- Genuine Wacker Neuson OEM Part — Sourced directly through the Wacker Neuson parts network, so you can order part number 5000119411 with full confidence in authenticity and application accuracy.
An O-ring is a molded loop of elastomer used to create a pressure-tight seal between two mating surfaces or around a shaft or port. In trash pump applications like the PT3 series, O-rings are found at housing joints, inlet and outlet connections, and internal fluid passages — anywhere a leak-free seal is needed to maintain suction and discharge pressure. When an O-ring hardens, cracks, or deforms due to age, heat, or chemical exposure, it loses its ability to compress and seal correctly, resulting in air ingestion, loss of prime, or fluid leaks that can quickly sideline the machine. Replacing a worn O-ring with the correct OEM-spec part restores the seal and brings the assembly back to full operating condition.
