What is the thickness of stainless steel tubing?

The thickness of stainless steel tubing can vary widely depending on the specific application and requirements. Generally, stainless steel tubing is available in various thicknesses, commonly measured in wall thickness (or gauge). Here are some typical wall thicknesses for stainless steel tubing:

Standard Gauge Sizes:

20 gauge: 0.035 inches (0.89 mm)
18 gauge: 0.049 inches (1.24 mm)
16 gauge: 0.065 inches (1.65 mm)
14 gauge: 0.083 inches (2.11 mm)
12 gauge: 0.109 inches (2.77 mm)

Schedule Sizes (for pipe sizes, commonly used in plumbing and industrial applications):
Schedule 5: 0.065 inches (1.65 mm) for 1/2" nominal size
Schedule 10: 0.083 inches (2.11 mm) for 1/2" nominal size
Schedule 40: 0.109 inches (2.77 mm) for 1/2" nominal size
Schedule 80: 0.147 inches (3.73 mm) for 1/2" nominal size

These are just a few examples, and the exact thickness required would depend on factors such as the specific use case, pressure requirements, and material grade. For precise specifications, it's always best to refer to the manufacturer's datasheet or industry standard.
