108WN  (RD3474  O Ring)

Genuine Shimano O Ring (part #108WN) — a rubber sealing ring that prevents water, salt spray, and debris from entering the reel body. When this O-ring dries out, cracks, or loses elasticity, moisture infiltrates the reel internals, causing corrosion to bearings, gears, and other critical components.
