The Honda 91408-890-780 Cord Tube (25MM) is a genuine OEM component designed for E4500 and ES4500 generators, G300 and G400 horizontal shaft engines, GX640 horizontal shaft engines, and H4514 lawn tractors. As a direct Honda replacement, this cord tube carries the exact dimensions and material specification Honda engineers matched to this application — including the 25MM sizing that distinguishes it from other tube variants in the catalogue. Confirm your machine's model and serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and the correct variant matters.
Key Features
- Genuine OEM Sizing — sourced directly from Honda, the 25MM designation is a precise variant identifier; verify it matches your unit's catalogue listing before purchase
- Broad Cross-Equipment Compatibility — listed for E4500 and ES4500 generators, G300 and G400 horizontal shaft engines, GX640 horizontal shaft engines, and H4514 lawn tractors, including models across Honda's engine and equipment lines
- Serial Number Verification Recommended — Honda updates part listings at production breaks; check your serial number against the fitment table to confirm this is the correct tube for your specific unit
- Correct Routing Protection — a properly fitted cord tube keeps wiring and cables routed and protected as Honda designed, preventing chafing or misrouting that can lead to electrical faults over time
A cord tube is a protective sleeve or conduit used to guide and shield electrical wiring or control cables through or around a machine's frame, housing, or body panels. It prevents the cable from contacting sharp edges, hot surfaces, or moving components that could wear through the insulation over time. When a cord tube cracks, splits, or goes missing, the cable it protects becomes vulnerable to abrasion and heat damage, which can result in intermittent electrical faults or outright wiring failure — making replacement straightforward but important preventive maintenance.
