Makita 423458-0 Spare Part - GASKET EN4950H/EN4951SH
Genuine Makita gasket 423458-0 — a thin, molded gearcase/gearbox sealing gasket designed to sit between the gearbox halves on Makita pole and petrol hedge-trimmer attachments. It restores the original seal that keeps oil, fuel residue and cutting debris out of the gearbox and mounting cavity, helping the drive components run quietly and smoothly. Fits a range of Makita attachment models including EN4950H, EN4951SH / EN4951H, EN401MP, EN420MP and related pole/hedge trimmer assemblies. This is listed and sold as the correct original Makita replacement for those gearcase applications, and is the exact part referenced on Makita parts diagrams and service lists.
Note: supplied as a single gasket (sold per unit), ready to drop into the gearbox joint during reassembly; if you’re replacing a failing seal, this genuine Makita spare part will match the original shape and mounting holes.
If you need other Makita spare parts for the same model, the parts diagram for EN4950/EN4951-series attachments shows this gasket as the gearcase sealing item.
