Smooth-Bore Seamless Stainless Steel Tubing
Seamless construction with no weld bead gives this tubing an interior with unrestricted flow. It is stronger than welded tubing and can be flared without splitting.
304 stainless steel has very good corrosion resistance.
316 stainless steel offers excellent corrosion resistance.
Tubing that meets ASTM specifications adheres to international standards for dimensions and materials.

High-Polish Stainless Steel Tubing for Food, Beverage, and Dairy
The interior and exterior are polished to a high-luster finish to resist particle buildup and allow for easy cleaning. Tubing is welded with a smoothed weld bead on the inside.
304/304L stainless steel tubing has very good corrosion resistance. 316L stainless steel tubing has excellent corrosion resistance.
Note: Ra measures the smoothness of the tubing; the lower the Ra value, the smoother and more polished the surface.

High-Polish Stainless Steel Tubing for Pharmaceuticals with Certification
- Temperature Range: -420° to 1500° F
- Bending Method: Tube Bender
- Compatible Tube Fittings: High-Polish Quick Clamp
This premium-grade tubing is polished to a high-luster finish to reduce particle buildup and allow for easy cleaning. It has excellent corrosion resistance. 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. Tubing comes with a traceable lot number and material test report.
Welded tubing is more economical than seamless tubing; it has a smoothed weld bead on the inside.
Note: Ra measures the smoothness of the tubing; the lower the Ra value, the smoother and more polished the surface.

General Purpose Aluminum Tubing
- Temperature Range: -450° to 400° F
- Bending Method: Tube Bender
- Compatible Tube Fittings: Flared
This tubing is lightweight with good corrosion resistance and weldability. It has magnesium and silicon added for strength. Tubing is seamless, which provides a smooth interior for unrestricted flow. It can be flared without splitting.

Vacuum-Rated Large-Diameter Aluminum Tubing
- Temperature Range: Not Rated
- Bending Method: Tube Bender
- Compatible Fittings: Vacuum
Move bulk material, exhaust gas, or suck up dust in powerful vacuum systems—this tubing is large enough to transfer pellets and debris and strong enough to withstand nearly perfect vacuum. Made of aluminum, it’s lighter weight than steel tubing, so it’s best when you need to reduce the weight of your system. It also resists corrosion from frequent rinsing, humidity, and rain. Nonmagnetic, it won’t disrupt sensitive equipment. This tubing isn’t welded, which means it’s free of weak spots and ridges that could obstruct flow.
