AirCraft Air Impact Wrench Service Kit – Housing & Valve (25–28 / 37 / 40) for AT0004 (AT0004-SK06)
At a Glance: Main housing and air-control valve service kit for the AirCraft AT0004, designed to restore sealing, fitment and smooth trigger/airflow control.
The housing is the backbone of the tool—holding the motor, impact section and handle together—while the valve system controls airflow, direction and trigger response. If the housing is damaged, threads are stripped, or the valve parts are worn, you can end up with leaks, sticky triggering, weak output or inconsistent speed. The AirCraft AT0004-SK06 housing and valve service kit replaces the key components (reference 25–28, 37 and 40), giving your AT0004 a fresh foundation and renewed air control for clean, dependable performance on the job.
A worn valve can waste air and make the tool feel unpredictable, while a compromised housing can cause misalignment and poor sealing at multiple points. Replacing both housing and valve-related parts is a smart move when you want a proper “reset” on the tool’s structure and air management.
