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.

AirCraft SG-A138 Seal Refresh – Fix Leaks, Bring Back Smooth Control

Fresh O-rings help the airbrush hold pressure correctly, improving spray consistency and reducing the frustration of leaks and unpredictable performance.

Extra Information

Common signs you need new O-rings: air leakage, bubbling, inconsistent spray, spitting, or fluctuating pressure.
Cleaning tip: Avoid harsh solvents on rubber seals unless the seals are rated for it—some solvents can swell or degrade O-rings.
Install carefully: Avoid stretching O-rings too much and ensure each ring sits flat in its groove.
Light lubrication: A tiny amount of airbrush-safe lubricant can help seals seat properly and last longer.
Test after fitting: Run clean air first to confirm sealing, then flush with cleaner/water before spraying paint.

Pro Tip

Replace O-rings one section at a time and test as you go—this makes it easy to identify which seal was causing the leak or performance issue.
