Original Hitachi O‑ring (B) — Part No. 322802. A small molded rubber sealing ring (type “O”) used in the piston / valve area of Hitachi rotary hammers; it’s the exact replacement listed in Hitachi parts diagrams for the DH24 series.
Fits example models such as DH24PC3, DH24PB3 and DH24PF3, and DH24PD3, DH25DL, DH25DAL and DH36DL.
What you’re getting: the original Hitachi-numbered O‑ring 322802 (sold as the single sealing ring used at the piston / gland location in the diagram). It’s intended to restore the factory seal and fitment so the hammer assembly returns to leak‑free operation.
If you’re replacing the internal seal on a DH24-series tool, this genuine Hitachi part is the direct match called out on the diagrams and belongs in any Hitachi spare parts selection for those models.
