Hitachi 885‑283 — original Hitachi O‑ring (I.D. 66.27 mm)
Description: A genuine Hitachi rubber sealing O‑ring engineered to restore the cylinder/plunger seal in Hitachi framing and concrete nailers. Used in Hitachi model NR90 —internal diameter 66.27 mm—so it slips into the cylinder groove to replace a worn or flattened seal and bring back reliable compression and firing consistency.
Fits (example models): commonly used in Hitachi/Metabo HPT / HiKoki NR90GC, NR90GC2, NR90GR, NR90GR2 and compatible NC40G / GFN3490 nailers. Confirm fit by matching part number 885‑283 and the I.D. 66.27 mm in your model’s parts list before installing.
