Precision Seamless Tubing

The Leader in Precision Seamless Tubing

We can produce 12 ft lengths of precision tubing and cannulated bar with internal diameters as small as 0.170” and Total Runout of 0.004”. It’s the most precise tubing in the world offered in the longest lengths. They said it couldn’t be done; but now you can go from our tubing to finished components off of your screw machine or lathe in a single step. No more need for secondary gundrilling operations. No mill run of material or long lead times required.
