Welcome to Columbia River Mandrel Bending.

We are a production tube bending company, located in Saint Helens, Oregon. We are family owned and operated, and have been in business since 2003. We employ between 10 and 15 people depending on the season, and produce well over a thousand bends a day on our four production tube benders. 

Unlike many tube bending companies, we stock an enormous inventory of our bent mandrel exhaust product for immediate delivery to our customers. In fact we have one of the largest stocked mandrel bend inventories in the country. We currently stock over 60,000 bends, which are immediately available through our online catalog.

Along with mandrel bends, we are now stocking a large inventory of related items. We now stock collectors, flex tubes, v-band assemblies, silicone hose products and other exhaust & fabrication related items. 

If you have custom part needs, please don't hesitate to send us a print or give us a call. We have full fabrication capabilities, and specialize in automotive tube assemblies.
