Polished to a 10 Ra finish on the inside, this tubing has the smoothest interior of any tubing we offer. Tubing comes with a traceable lot number and material test report. It is welded with a smoothed weld bead on the inside to reduce particle buildup and allow for easy cleaning. Tubing is commonly used in semiconductor applications or anywhere surface contamination is a concern. It has excellent corrosion resistance. Tubing comes in a plastic sleeve.

Note: Ra measures the smoothness of the tubing; the lower the Ra value, the smoother and more polished the surface.

This premium-grade tubing is polished to a high-luster finish to reduce particle buildup and allow for easy cleaning. Tubing has excellent corrosion resistance. It is welded with a smoothed weld bead on the inside to reduce particle buildup and allow for easy cleaning. Tubing with interior smoothness of 20 Ra is capped, put in a plastic sleeve, then sealed in a cardboard tube. Tubing with interior smoothness of 15 Ra comes in a plastic sleeve. All come with a traceable lot number and material test report.

Note: Ra measures the smoothness of the tubing; the lower the Ra value, the smoother and more polished the surface.

Also known as Inconel, this tubing has the highest temperature rating of all the non-stainless steel tubing we offer. It has excellent corrosion and chemical resistance. It’s also seamless—the smooth interior won’t restrict flow. You can flare the ends without splitting the tubing, and weld to connect. All sizes meet ASTM B163, which is an international standard for tubing dimensions.

From cookware to chemical-processing equipment, 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.

304/304L stainless steel contains less carbon than standard 304 for better weldability.

Welded round tubes are more economical than seamless tubes. Seamless round tubes are more corrosion resistant than welded tubes because they don’t have a seam that could potentially introduce impurities.

Polished to either a brushed or mirror-like finish, this material is widely used to fabricate decorative enclosures and industrial workstations. The polished surfaces are covered with a protective peel-off film. 304 stainless steel is a good all-around choice for a wide range of applications. It maintains its corrosion resistance in temperatures up to 1500° F.

Mirror-like #7 finish is reflective with some visible grain lines. Rectangular and round tubes are polished on the outside.

The addition of molybdenum gives 316 stainless steel excellent corrosion resistance. Use it in a variety of marine and chemical-processing applications. It maintains its corrosion resistance up to the maximum temperature.
