The Multiquip 0489402910 is a genuine OEM Casing O-Ring designed for QP2TH, QP2TB, QP2TK, and QP2TZ series pump equipment. As a factory-sourced component, this O-ring meets the original material and dimensional standards required for proper pump casing sealing. It is a direct-fit replacement confirmed for QP2TH, QP2TB, QP2TK, and QP2TZ models, making it a dependable choice when servicing your Multiquip pump. Keep part number 0489402910 on hand to minimize service interruptions during routine maintenance or emergency repairs.
Key Features
- Genuine OEM Sealing Material — Manufactured to the original compound and durometer specification, ensuring the O-ring compresses and seals correctly against the pump casing surfaces.
- Drop-In Casing Fit — Sized to seat directly in the casing groove without trimming or reshaping, maintaining the correct compression depth on reassembly.
- Broad Pump Compatibility — Fits QP2TH, QP2TB, QP2TK, and QP2TZ models, covering both trash pump and centrifugal pump variants in the QP2T series.
- Leak-Free Pump Operation — A properly seated casing O-ring maintains internal pressure and prevents fluid from bypassing the impeller housing, sustaining peak pump output and flow rate.
- Fuel and Fluid Resistance — OEM material selection ensures the ring resists degradation from prolonged exposure to water, sediment-laden fluids, and the operating temperatures common in pump applications.
The casing O-ring creates a pressure-tight seal between the pump casing halves, preventing fluid from escaping around the impeller chamber during operation. Without an intact seal at this joint, the pump loses internal pressure, resulting in reduced flow, loss of prime, and potential housing damage from vibration and cavitation. Replacing a worn or damaged casing O-ring with the correct OEM part — 0489402910 — restores the pump's ability to move fluid efficiently and protects the surrounding casing components from accelerated wear.
