Description
Overview:
This oil seal is a genuine Honda part for small 4‐stroke engines used in handheld garden and construction equipment. Supplied under MPN 91212-Z3E-003, it provides a tight barrier around a rotating engine shaft to keep engine oil in and dirt and moisture out. The seal body is a durable oil‐resistant elastomer with a metal reinforcement and a spring‐loaded lip for consistent contact on the shaft. It is suitable for Honda HHB25E leaf blowers and other tools powered by GX25 and GX35 series engines. Using the correct OEM seal helps prevent oil leaks that can lead to premature wear, mess, and downtime, and supports smooth, efficient running over long service intervals. Genuine Honda part.
