Original Hitachi O‑ring — part no. 998414. A small elastomer sealing ring used in Hitachi / HiKOKI demolition hammers and related impact tools; it’s the factory-listed “O‑RING (A)” replacement to restore proper piston/valve sealing and stop air or oil leaks.
Examples of models where this part appears on the exploded diagrams and parts lists include H65SB / H65SB2 / H65SB3, H65SD , H65SD3 and H70SA — order the exact part number 998414 to ensure correct fit.
Supplied as the single genuine Hitachi replacement O‑ring, it matches the original form and fit so you can get the tool back to service quickly; keep the part number handy when replacing seals or doing routine maintenance on older demolition hammers and other parts for power tools.
