The Wacker Neuson 30307 O-Ring is a genuine OEM sealing component designed for the PT2 series 50mm/2in centrifugal trash pumps. As a direct factory replacement, this O-Ring is manufactured to the exact material grade and dimensional tolerances required to maintain a leak-free seal within the pump assembly. Confirmed fitment covers the PT2Y, PT2A, PT2B, PT2R, and PTK2 pump models, including the PTK2 engine-less variant. Keeping the correct O-Ring in place is essential to sustaining pump output pressure and preventing fluid ingress at critical mating surfaces.
Key Features
- Correct Compound and Dimensional Spec — Manufactured to the exact durometer and cross-section required for the PT2 pump's sealing surfaces, ensuring proper compression and fluid containment.
- Drop-In Seal Replacement — Seats directly into the OEM groove without trimming or adjustment, restoring a positive seal at the mating joint.
- Broad PT2 Series Coverage — Fits PT2Y, PT2A, PT2B, PT2R, and PTK2 50mm/2in centrifugal trash pump models, including the engine-free PTK2 configuration.
- Sustains Pump Pressure and Output — A correctly seated O-Ring maintains the internal pressure differential needed for efficient water transfer; a degraded or missing O-Ring leads to pressure loss and fluid bypass.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, part number 30307 meets the same material and quality standards as the original component installed at the factory.
An O-Ring in a centrifugal trash pump serves as a static or dynamic seal at critical joints within the pump housing, volute, or port connections. It prevents fluid from bypassing internal chambers or leaking externally, which is essential for maintaining the suction and discharge pressure the pump relies on to move water and debris efficiently. When an O-Ring deteriorates — through chemical exposure, heat cycling, or compression set — it loses its ability to conform to the mating surfaces, causing pressure loss, visible leaking, or cavitation that can accelerate wear on surrounding pump components.
