What Is This?

A Teflon O-ring specifically sized for the paint cup seat — the junction where the cup meets the airbrush body. The cup gets the most direct chemical exposure during cleaning, which is exactly why Teflon matters here: standard rubber swells or hardens with repeated solvent contact, Teflon doesn't.

When You Need This Part

⚠️ Paint leaking at cup base — seeping around cup-to-body joint during use

⚠️ Cup feels loose or unstable — wobbles against the body

⚠️ Visible O-ring damage — cracking, flattening, or hardening

🔄 Routine service — every 3–6 months under heavy use

⚠️ Heads Up

Cup seal only — not interchangeable with body, nozzle, or valve O-rings on the same airbrush.

Confirmed for the four listed models. If unsure, check the exploded parts diagram for your airbrush.

Notes · Q & A

What nozzle size do I need for miniatures?

0.3mm is the versatile all-rounder for base coats and priming; 0.2mm suits fine detail work. Larger nozzles (0.5mm) are for terrain and big surfaces.

Do I need a compressor with a tank?

A tank smooths the airflow and reduces pulsing, giving more consistent results — worth it if you spray regularly, but tankless compressors work fine for occasional use.

How do I keep an airbrush working well?

Flush with airbrush cleaner between colours and strip-clean after each session. Most spraying problems are cleaning problems.
