Description
Overview:
This is a Genuine Makita O Ring, part number 213047-7, designed to maintain a tight, dependable seal inside Makita sheet orbital sanders such as the BO3700 and BO4900V. The circular rubber ring helps contain lubricants and block dust ingress in key assemblies, supporting smooth running and consistent performance. Made from durable rubber and sized to Makita specifications, it seats correctly in the designated groove and restores sealing effectiveness when the original ring has hardened, flattened, or torn. A sound seal reduces vibration-related wear, protects internal components, and helps keep sanding results even and predictable. Suitable for routine maintenance or repair, this O Ring is a direct-fit replacement for the specified Makita models and is an essential small part that supports the overall reliability of your sander.
