The Multiquip 0481310950 is a genuine OEM O-Ring Volute Casing G95 designed for QP402H and QP402B centrifugal dewatering pumps. As a factory-authorized replacement, this O-ring meets the same dimensional and material standards as the original component installed at the factory, ensuring a proper seal at the volute casing joint. This part is sourced directly through Multiquip's OEM supply chain, giving you confidence in fitment and material quality. If you're servicing a QP402H or QP402B and need to restore a reliable housing seal, part number 0481310950 is the correct replacement.
Key Features
- Precision-Molded Sealing Grade: — G95 designation confirms the correct compound grade and cross-sectional profile to maintain a leak-free seal at the volute casing interface under pump operating pressures.
- Direct-Fit Volute Casing Replacement: — Sized and profiled to seat correctly in the casing groove without trimming or modification, allowing straightforward installation during pump disassembly and reassembly.
- Genuine OEM Part: — Manufactured to Multiquip's original equipment specification, ensuring material compatibility with the pump housing and the fluids handled by QP-series centrifugal pumps.
- Compatible with QP402H and QP402B: — Verified fitment for both the Honda-engine and Briggs and Stratton Vanguard-engine variants of the QP402 centrifugal pump series.
- Critical Pump Integrity Component: — A worn or damaged volute casing O-ring allows water to bypass the sealed housing joint, causing pressure loss, inefficient pumping, and potential casing damage if left unaddressed.
The volute casing O-ring forms a pressure-tight seal between the pump's volute housing sections, preventing water from escaping the casing at the joint during operation. Without an intact seal at this location, the pump loses the ability to maintain prime and deliver consistent flow and pressure output. Over time, heat cycling, chemical exposure, and compression set cause the O-ring material to harden or deform, making periodic replacement an essential part of pump maintenance.
