At a Glance: Replacement O-ring seal kit for SG A180—fixes air leaks, improves control and keeps your spray consistent.
If an airbrush starts acting “moody” — inconsistent spray, tiny air leaks, paint pulsing or a trigger that doesn’t feel right — worn seals are often the hidden culprit. The AirCraft SG A180-04 O-ring repair kit refreshes key sealing points in the SG A180 airbrush, replacing the O-rings referenced as parts 4, 6, 7, 12, 25, 28, 35 and 37. Fresh O-rings help restore airtight performance, stabilise airflow and keep paint delivery smooth so your lines stay crisp and your shading stays silky.
Airbrushes rely on tiny, airtight passages. When O-rings harden, swell or crack (often from age or harsh cleaners), you can get leaks, reduced responsiveness and unpredictable spray patterns. Replacing seals is one of the quickest ways to bring an SG A180 back to reliable, controllable operation.
