10J6D  (RD16326  Spool Support Seal)

Genuine Shimano Spool Support Seal (part #10J6D, RD16326) — the spool support seal creates a watertight barrier around the spool support area, preventing saltwater, sand, and contaminants from reaching the internal bearings and drag components. A compromised seal allows corrosion to develop on critical internal surfaces, leading to rough drag performance, bearing failure, and costly reel damage. Cross-references with Shimano part numbers 10J6D and RD16326. OEM replacement ensures perfect fit and factory performance.
