This is a surplus TB Woods 6E EPDM Sure-Flex Plus rubber coupling sleeve—a two-piece design used in power transmission systems to connect shafts and absorb vibration. Made from EPDM rubber, it’s flexible, durable, and resistant to wear. It fits matching Sure-Flex coupling hubs and helps reduce shock loads, misalignment issues, and noise in industrial drives. Packaging may show wear or be incomplete, but the sleeve itself is unused and ready to install. Ideal for maintenance, repair, or OEM replacement in conveyor, pump, fan, or motor applications. Always verify compatibility with your existing coupling setup before purchase.
