O-RING KIT FOR SG A138

AirCraft SG-A138-04 O-Ring Kit – For SG-A138 Airbrush

At a Glance: Replacement seal kit for the SG-A138 airbrush—helps prevent leaks, stabilise pressure and keep spraying consistent.

Airbrushes run on tiny tolerances and controlled airflow, so when an O-ring wears out the symptoms show up fast: air leaks, bubbling, inconsistent paint flow, spitting or a trigger that suddenly feels “off”. Even a small seal can have a big impact because it affects pressure stability and how smoothly the airbrush regulates air and paint.

The AirCraft SG-A138-04 O-ring kit is designed for the AirCraft SG-A138 airbrush and replaces worn or damaged sealing rings to restore reliable performance. It’s ideal for routine maintenance, rebuilding an older airbrush, or troubleshooting leak-related issues that cleaning alone can’t fix.
