The Multiquip 9454004010 is a genuine OEM O-Ring 4mm GX240 340K1 HC- designed for Multiquip gasoline-powered generators and arc welders, including the GA6HZ, GA3.6HZ, GA3.6HA, GA6HB, GA6HEB, and GA3.6HR generator series, as well as GAW180HE, GAW180HE1, and GAW180HEA welder models. As a direct Multiquip OEM part, the 9454004010 is manufactured to the exact material and dimensional specifications required for proper sealing in Honda GX240 and GX340K1 engine applications. Sourcing the correct O-ring by part number matters here — even minor dimensional variations can compromise the seal and lead to fluid leaks or pressure loss. Keep part number 9454004010 on hand as a routine service spare to stay ahead of wear-related failures during maintenance intervals.
Key Features
- Exact OEM Material Specification — Manufactured to the precise durometer and cross-section dimensions required for Honda GX240 and GX340K1 engine sealing applications.
- Drop-In Service Replacement — Dimensioned to seat directly into the original groove without stretching, trimming, or modification, ensuring a consistent seal on reinstallation.
- Broad Fitment Across Generator and Welder Lines — Confirmed for GA6HZ, GA3.6HZ, GA3.6HA, GA6HB, GA6HEB, GA3.6HR generators and GAW180HE, GAW180HE1, GAW180HEA arc welders.
- Leak Prevention at Engine Interfaces — A correctly seated O-ring maintains fluid and pressure containment at critical engine junctions; a degraded or incorrectly sized ring risks seepage that can escalate into engine damage.
- Fuel System Integrity — Used within the fuel circuit of GX-series engines, this O-ring directly affects safe fuel containment — using the correct OEM part ensures no compromise to fuel system tightness.
An O-ring is a circular elastomeric seal that sits within a machined groove to prevent the passage of fluids or gases between mating components. In Honda GX240 and GX340K1 engines — as found across Multiquip's GA-series generators and GAW-series arc welders — O-rings are used at fuel system junctions and engine assembly interfaces to maintain a reliable, leak-free seal under operating temperatures and pressures. When an O-ring hardens, cracks, or deforms with age, it loses its ability to compress evenly in the groove, allowing fuel or oil seepage that can create safety hazards and lead to internal engine contamination if left unaddressed.
