Dura-Tube® is a suite of products produced using our trepan process. Available in a variety of outside diameters (O.D.), inside diameters (I.D.), wall thickness, lengths, and grades, Dura-Tube conforms to ASTM specifications.

Most machined parts require boring a hole—a time-intensive machining operation. Dura-Tube products mitigate the need for hole boring, saving time; and since Dura-Tube weighs less than a standard bar, customers will also benefit from lower freight costs, saving time and money. Dura-Tube is perfect solution for Oil and Gas (e.g. slips, bit sleeves), Transportation (e.g. cylinder liners, sheaves, bushings), and Power Transmission (e.g. pulleys, shaft adapters) applications.

Dura-Tube vs. Centrifugal and Static Castings

Dura-Tube is an ideal alternative to centrifugal and static castings.

Dura-Tube is produced from our continuous cast solid round bar, therefore, the chemical, mechanical and microstructure results will be the same as Dura-Bar continuous cast solid round bar in comparable sized diameter..

Dura-Tube outperforms centrifugal and static castings in quality, total machining time, better O.D. clean-up stock, porosity, pattern costs and is backed by Dura-Bar's Zero Defect Guarantee.
