What Is This?

Precision Teflon (PTFE) O-rings for sealing the critical junctions inside the airbrush — paint cup, nozzle assembly, and valve sections. Teflon resists swelling, hardening, and degradation from solvents and aggressive cleaners far better than standard rubber O-rings.

Where They Seal

🫙 Paint cup — seals cup-to-body junction, prevents leaks under pressure

🔧 Nozzle/needle assembly — prevents air and paint blowback into body

💨 Valve sections — maintains airtight integrity in trigger area

When You Need New O-Rings

⚠️ Paint leaking from cup base or nozzle area

⚠️ Air leaking at body joints

⚠️ Erratic atomisation despite clean nozzle and needle

🔄 Routine maintenance after extended heavy use

⚠️ Heads Up

O-rings are precision-sized — will not seal correctly if fitted to a model they weren't designed for. Verify your model before ordering.

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.
