109EB (O-Ring - Check Cross Compatibility)

Genuine Shimano O-Ring (part #109EB) — this O-ring provides a watertight seal within your Shimano reel, protecting internal bearings and components from saltwater intrusion, dirt, and debris. A worn, cracked, or missing O-ring allows contaminants to reach sensitive internal parts, leading to corrosion, bearing failure, and reduced reel lifespan. Cross-references with Shimano part numbers 109EB, BNT0188, and TGT0185 — check cross-compatibility with your specific reel model. OEM replacement ensures perfect fit and factory performance.
