The Multiquip 0459220120 is a genuine OEM Seal Washer (Casing) M12 designed for Multiquip QP-series trash and centrifugal pump models including QP2TH, QP3TH, QP3TS, QP3THX, QP3TK, QP2TK, QP2TZ, QP3TZ, QP3TB, and QP2TB. As a direct OEM component, 0459220120 is manufactured to the same standards as the original part, ensuring a correct sealing interface at the M12 casing position. Sourced directly through authorized Multiquip distribution channels, this seal washer is a straightforward service item to keep your pump operating leak-free and at full efficiency.
Key Features
- OEM-Grade Sealing Material — Manufactured to the original compression and material specification for the M12 casing position, delivering consistent sealing performance across pump cycles.
- Drop-In Casing Fit — Dimensioned to the exact M12 thread and casing seat geometry, seating correctly without adjustment during reassembly.
- Broad QP-Series Compatibility — Confirmed fitment across QP2TH, QP3TH, QP3TS, QP3THX, QP3TK, QP2TK, QP2TZ, QP3TZ, QP3TB, and QP2TB pump models.
- Leak Prevention at the Casing Joint — A correctly seated seal washer maintains the pressure boundary at the casing interface; a worn or missing washer allows fluid bypass and pressure loss that degrades pump output.
- Genuine OEM Part — Supplied as part number 0459220120 directly within the Multiquip OEM parts chain, giving you confidence that the component matches the original engineering specification.
A casing seal washer creates a fluid-tight barrier at the bolted joint between pump casing sections, preventing water or slurry from escaping around the fastener during pressurized operation. Without an intact seal washer at this location, the pump can develop a weeping leak at the casing joint that worsens over time and reduces the discharge pressure available at the outlet. Replacing a worn or damaged seal washer as part of routine pump service restores the integrity of the casing assembly and protects surrounding components from moisture-related deterioration.
