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. 

Dura-Tube can be utilized in several industries, including (but not limited to) slips and bit sleeves in oil and gas applications as well as cylinder liners, sheaves and bushings in automotive/transmission applications.
