Adapters & Stems

The connective tissue of your aerosol setup.

This collection covers stems and adapters that bridge caps, valves, and spray systems — including Flow-Ctrl stems, BottleNecks, BOOGER (4mm to 1/8"), STINGER brass stems, and Japanese FatCap / FadeBomb adapters.

Use these to fine-tune flow, mate skinny caps to the right stem, or connect modular nozzle bodies. If you’re building a custom stack, start here.
