We are currently experiencing substantial delays with Hitachi/HiKOKI and Metabo spare parts due to the two brands merging warehouse. At this moment in time we are unable to provide confirmed delivery dates on out of stock parts, for any urgent requirements please contact us prior to ordering.
Original Hitachi O‑ring — part no. 956996 (listed as O‑RING 1AS‑60). This small sealing ring is used on Hitachi / Metabo HPT / HiKoki demolition and rotary hammers to seal the cylinder/case area and prevent air/oil leaks that degrade hammer performance.
Key details: O‑ring size 59 × 2 mm (1AS‑60), made of NBR (nitrile) with ~70 hardness — a durable material choice for hammer service conditions. Sold individually and intended as a direct replacement for the original Hitachi seal.
Example models this part is documented to fit: H65SB / H65SC, H50SA, H60MR, H70SA, DH40SR, DH45MR, DH38MS and DH28Y Hitachi / HiKOKI demolition‑hammer models. Use this O‑ring when you need to restore proper sealing and impact performance in those tools.
