The Multiquip 0481572500 is a genuine OEM Volute Casing O-Ring designed for QP4TH, QP4TZ, QP4TKT, QP4TB, and QP4TK series trash pumps. As a factory-original component, it is manufactured to the exact material grade and dimensional tolerances required to maintain a proper seal at the volute casing interface. Sourced directly through Multiquip's authorized parts program, this O-Ring ensures a correct fit with no guesswork on compatibility. If you're servicing any of the QP4T-series trash pumps, this is the correct OEM replacement seal for the job.
Key Features
- OEM-Grade Elastomer Material — Manufactured to the original compound specification for correct compression set and resistance to the abrasive, debris-laden fluids handled by trash pumps.
- Drop-In Volute Casing Fit — Seats directly into the volute casing groove as designed, restoring the original sealing surface without machining or modification.
- Broad QP4T-Series Coverage — Confirmed fitment across QP4TH, QP4TZ, QP4TKT, QP4TB, and QP4TK trash pump models.
- Leak-Free Pump Operation — A correctly seated volute casing O-Ring maintains internal pressure and prevents bypass, keeping pump output at full rated capacity.
- Genuine Multiquip OEM Part — Part number 0481572500 is sourced through Multiquip's authorized supply chain, ensuring you receive the correct part the first time.
The volute casing O-Ring creates a pressure-tight seal between the pump's volute casing halves or between the casing and pump body, preventing water and slurry from bypassing the impeller or escaping the pump housing. When this seal is intact, the pump maintains the suction and discharge pressure needed to move debris-laden water efficiently. A worn, cracked, or flattened O-Ring causes pressure loss, visible leakage at the casing joint, and a noticeable drop in pumping performance — making timely replacement essential during any pump service or rebuild.
