The Honda 91202-Z1T-003 Oil Seal (25X41X6) is a genuine OEM component designed for a wide range of Honda engines, generators, inverter generators, water pumps, two-stage snow blowers, and tillers, including GX160 and GX200 horizontal shaft engines, EB2500, EB3000, EM2500, EM3000, and EP2500 generators, the EU3000 inverter generator, WB20, WB30, WH15, WH20, WMP20, WT20, and WT30 water pumps, HS724 and HSS724 two-stage snow blowers, and the FC600 tiller. As a direct Honda OEM part, it is manufactured to the same specification as the original seal it replaces. Verify your unit's serial number against the fitment table to confirm this is the correct seal for your machine before ordering.
Key Features
- Genuine OEM Sealing Integrity — sourced directly from Honda, this seal matches the original dimensional profile (25 x 41 x 6 mm) for a leak-free fit without reworking the bore or shaft.
- Cross-Equipment Fitment — listed for Honda GX160 and GX200 horizontal shaft engines, multiple generator and inverter generator models, WT-series and WB-series water pumps, HS724 and HSS724 two-stage snow blowers, and the FC600 tiller.
- Serial Number Verification Recommended — Honda supersedes seals at production breaks, so confirm your machine's serial number against the fitment table to ensure part number 91202-Z1T-003 is the current correct seal for your unit.
- Leak Prevention — a degraded or damaged oil seal allows oil to escape past the shaft, leading to low oil levels, accelerated internal wear, and potential engine or pump failure; replacing it promptly restores a clean, dry running condition.
An oil seal is a precision-fit lip seal that prevents lubricating oil from escaping along a rotating shaft — such as a crankshaft output end or pump drive shaft — while also blocking dirt, dust, and moisture from entering the housing. It works by maintaining constant radial pressure against the shaft as it spins, forming a dynamic barrier between the lubricated interior and the outside environment. When an oil seal hardens, cracks, or wears, that barrier breaks down: oil leaks out, contaminants get in, and the bearings or other internal components that depend on clean lubrication begin to deteriorate rapidly.
