About Metal Tubing

Miniature Stainless Steel Tubing

Also known as hypodermic or needle tubing, this tubing has thin walls and is made to tight tolerances for use in precision applications.

Extreme-Pressure Miniature Stainless Steel Tubing

This tubing withstands high pressures up to 13,700 psi. It is also known as capillary tubing.

Miniature Stainless Steel Tubing with 90° Bend

This tubing has a 90° bend that holds its shape.

Miniature Stainless Steel
Tubing with Polished Exterior

The outside of this tubing is polished to a high-luster finish for a shiny appearance.

Miniature Stainless Steel Tubing for Corrosive Gases

A thin layer of silicon on the interior provides a smooth surface and offers protection against corrosive gases.

Precision Stainless Steel Tubing

This tubing is made to tighter tolerances than other stainless steel tubing.

Miniature Firm Plastic Tubing for Air and Water

Use this micro-sized tubing for delicate, precision applications.

Copper, Brass, and Bronze

Ultra-Formable 260 Brass Round Tubes

The most formable brass we offer, 260 offers better weldability than 300 series brass but it’s not as machinable. Sometimes called cartridge brass, it's commonly used for ammunition casings, radiator components, and decorative door hardware.

Weldable 122 Copper Tubes

The addition of phosphorus makes 122 copper easier to weld and braze than 110 copper. It has excellent resistance to corrosion caused by water, soil, and weather, making it the go-to material for plumbing and underground applications.

Miniature Heat-Shrink Tubing

The smallest heat-shrink tubing we offer, this tubing protects wire with a 0.017" and smaller diameter.
