DeWalt 321118 Spare Part - WASHER

Genuine Hitachi part 321118 — O‑ring (sealing ring) for reciprocating saws. This is a small, molded elastomer sealing ring used in the reciprocating/blade-holder area to restore the original seal and internal alignment in Hitachi/Hikoki saw assemblies.

Fits (example models): Hitachi CR13V, CR13V2 and CR13VC (these model diagrams list part 321118 as the O‑ring in the reciprocating assembly; some parts cross‑references also show equivalent listings for related brands).

Why this part matters: the 321118 O‑ring prevents internal play, keeps dust and debris from entering the mechanism, and maintains smooth blade action — an inexpensive, single‑component repair that often restores proper function without replacing larger assemblies. The part is supplied as the original Hitachi replacement item and is installed by pressing into the mating groove shown in the exploded diagram for your model.

Note: sold individually and intended as the factory replacement O‑ring — a small but essential power tool parts item to have when repairing a Hitachi CR13V-series reciprocating saw.
