KBS Rollobend System

Long-Radius Roller-Bearing Tubing Bender

Tubing Benders

for  Ultra-High Purity UHP Thin-Wall Electro-Polished Stainless Steel Tubing
For precise and reproducible bends on electro-polished stainless steel tubing.  Each tool bends up to 180 degrees.  Large radius bends are ideal for preventing smooth inside walls from crinkling, flaking and generating particulate contamination.  The open side slips over the tube at any point.  You get smooth long bends with no marking, scraping or flattening.  No need to figure spring-back – it’s been done for you.

Long Radius Tubing Benders

A Specified and Required Tool

If you are a contractor and / or a facility involved in high-purity orbital welding operations KBS Long Radius Tubing Benders are a specified and Required Tool.

A Savings of 10%

By bending the tubing, the expensive long tangent 90 degree fittings can be eliminated. This elimination has a realized a savings of 10 percent over a welded system on a average high-purity installation.


KBS Long Radius Tubing Benders have been specified and required by major micro-electronic manufacturing facilities for their high-purity process piping system installations throughout the United States and the world .
