The Multiquip 9454004018 is a genuine OEM O-Ring 4mm GX240 340K1 HC- designed for Multiquip gasoline-powered generator models GA3.6HZ, GA3.6HA, and GA3.6HR. As a direct OEM replacement, this o-ring is manufactured to the exact material and dimensional tolerances specified for these generators, ensuring a proper seal every time. Sourced directly through authorized Multiquip supply channels, part number 9454004018 is the correct sealing component to specify when servicing these units.
Key Features
- Exact OEM Sealing Dimensions — Manufactured to the precise 4mm cross-section and diameter spec required for the GX240 and 340K1 engine applications, ensuring full compression and leak-free seating.
- Genuine Multiquip OEM Part — Sourced directly from Multiquip, this component meets the same material grade and elastomer specification as the original part installed at the factory.
- Confirmed Fitment — Verified for use on GA3.6HZ, GA3.6HA, and GA3.6HR gasoline-powered generator models; part number 9454004018 cross-references HC-2280089 for straightforward identification.
- Leak Prevention at the Source — A correctly seated o-ring maintains fluid and pressure containment within the engine assembly; a worn or deformed o-ring allows seepage that can lead to engine damage or fluid loss over time.
- Drop-In Service Part — Sized to seat directly into the existing groove without modification, making it straightforward to include in routine engine maintenance or teardown rebuilds.
An o-ring is a precisely sized elastomeric seal that sits within a machined groove to prevent the passage of fluids or gases between mating components. In engine assemblies such as the GX240 and 340K1, o-rings are used at critical junctions — including fuel, oil, and coolant circuits — where a consistent, compressive seal is essential to safe and efficient operation. When an o-ring hardens, cracks, or loses its original profile, the seal degrades and leaks develop; replacing it with the correct part restores the integrity of the sealed joint immediately.
