💡 What is capillary tubing best used for in precision projects?

Capillary tubing provides a tiny, precise pathway for fluids or gases in compact builds, making it handy for hobbyists and small fabrication setups.

• Small-diameter routing for fluids and gases in micro systems
• 304 stainless steel resists corrosion and maintains form in moderate environments
• Ideal for DIY CNC, robotics, and prototype hardware
• Keeps tubing neat and aligned in custom assemblies
