This ProAiir snorkel cap is designed for use with siphon feed airbrushes. It fits bottles with a 20/410 neck, including 1, 2, and 4 oz ProAiir bottles. With a 20mm top fit, it's a versatile choice. The tube might be a bit long, so you can trim it to fit your bottle. Cutting the tube at an angle helps makeup flow smoothly into the airbrush.

Using this ProAiir snorkel cap is easy. First, find a siphon - feed airbrush and a 1, 2, or 4 oz ProAiir bottle with a 20/410 neck. Simply fit the cap onto the bottle. You'll notice the tube might be longer than what you need. Use a pair of scissors to trim the tube to the right length for your bottle. It's a good idea to cut the tube at an angle. This will allow the makeup in the bottle to flow easily into the airbrush. As for maintenance, after each use, take off the cap and rinse it with clean water. Make sure to dry it thoroughly before using it again. Keep it in a dry place when not in use to prevent any damage.
