Hitachi 886326 Spare Part - Actuator
Original Hitachi part 886-326 (listed as ACTUATER / actuator, part number 886326) — a direct-fit actuator assembly designed for Hitachi/Hikoki pneumatic/gas nailers. This compact replacement restores the trigger-to-valve actuation inside the tool so the firing sequence and valve response operate like new.
Key details
- Function: precision actuator assembly that links the trigger/actuation mechanism to the tool’s valve—responsible for consistent actuation of the firing/air/gas system.
- Fitment: used in Hitachi NT65-series nailers (NT65GS, NT65GA, NT65GB) and appears in parts lists for compatible gas brad/finish nailer models such as GBNF1850 and GBNT1665. Check your tool’s parts diagram to confirm location 886326.
- Supply: sold as a single replacement actuator unit intended as a like‑for‑like Hitachi part for repair and return-to-service.
Why this part matters
- Replacing a worn or broken actuator fixes intermittent firing, mis‑feeds, or a non‑responsive trigger without needing broader valve or body replacement.
- Because it’s the original Hitachi part number shown on manufacturer parts diagrams, it installs directly into the tool’s actuation assembly for a precise fit and correct alignment.
If your tool’s exploded diagram or parts list identifies 886-326 / 886326 as the actuator in the nose/valve area, this is the correct original Hitachi replacement to restore reliable operation.
