The Honda 15620-ZE2-700 Oil Filler Cap is a genuine OEM replacement designed for a wide range of Honda generators, including the EU2200, EB5000, EG4000, EM7000, EW140, and many more across the EU, EB, EG, EM, EW, EX, and EZ series. As a factory-original component, this cap is manufactured to Honda's exact specifications, ensuring a secure, leak-free fit on every compatible unit. Honda supersedes parts at production serial breaks, so confirm your generator's serial number against the fitment table before ordering to make sure part number 15620-ZE2-700 is the right cap for your machine.
Key Features
- Genuine OEM Sealing — sourced directly from Honda, this cap is engineered to seat and seal correctly on the oil filler neck, preventing oil leaks and keeping contaminants out of the crankcase.
- Direct-Fit Replacement — matches the original's thread pitch and retaining geometry, so it installs without modification on every compatible Honda generator model.
- Broad Generator Coverage — fits Honda inverter generators, conventional generators, and welder generators across the EU, EB, EG, EM, EW, EX, and EZ lines, including models such as the EU2200, EB3500, EG6500, EM5000, EW171, EX4500, and EZ5000.
- Serial-Range Verification Matters — Honda updates components at specific production breaks; check your unit's serial number against the fitment table to confirm this cap applies to your serial range.
The oil filler cap closes the oil fill port on a generator's engine, keeping the crankcase sealed during operation. A properly sealing cap holds oil in and keeps dirt, dust, and moisture out — both critical in the field environments where Honda generators are typically run. When a cap cracks, strips its threads, or loses its sealing gasket, oil can escape or become contaminated, leading to accelerated engine wear and potential engine damage during operation.
