The Multiquip 0481311000 is a genuine OEM O-Ring Socket G100 designed for QP402H and QP402B centrifugal pumps. Sourced directly from Multiquip, this replacement seal delivers the exact material grade and dimensional tolerancing required to maintain a leak-free connection at the socket interface. Confirm your pump model against the QP402H and QP402B fitment before ordering to ensure a direct, correct-fit installation. Keeping this seal in good condition is essential to sustaining pump efficiency and preventing fluid loss at the joint.
Key Features
- Exact-Grade Sealing Material — Manufactured to OEM compound and durometer specifications, ensuring the ring compresses and seals correctly at the socket joint without distortion or bypass.
- Genuine OEM Part — Supplied by Multiquip as an authorized OEM component, matching the original seal installed at the factory for a direct, tool-compatible swap.
- Confirmed Fitment — Verified for QP402H and QP402B centrifugal pumps; cross-reference your model code before installation.
- Leak-Free Socket Connection — A correctly seated O-Ring Socket G100 maintains full pressure at the socket interface, keeping pump output consistent and preventing moisture intrusion into connected components.
- Fuel and Fluid System Integrity — A worn or degraded O-ring at this location can result in visible leaks, pressure drop, and potential damage to surrounding pump housing — replacing it promptly restores safe, compliant operation.
An O-ring is a loop-shaped seal that sits within a machined groove at a joint or socket, compressing under assembly pressure to form a fluid-tight barrier. In a centrifugal pump, socket O-rings like the G100 prevent water or fluid from escaping at connection points between pump sections or discharge fittings. When an O-ring hardens, cracks, or deforms with age and heat cycling, the seal fails — leading to leaks, loss of prime, and reduced pump performance. Replacing this component with the correct OEM part restores the integrity of the seal and protects the surrounding pump assembly from moisture damage.
