KBS Tubing Benders
Bend Steel, Stainless Steel, Aluminum, Brass, Soft and Some Hard Copper and Titanium
- Each tool bends up to 180 degrees and large radius bends are ideal for preventing smooth inside walls from cracking, flaking and generating particulate contamination.
- The open side slips over the tubing at any point. You get smooth long bends with no marking, scraping or flattening.
About Us
In the mid 1980's a well known semi-conductor fabrication facility in silicon valley was experiencing a 40% rejection rate of their chips due to particulate contamination in their process piping caused by bending tubing with standard radius tubing benders.
A contractor installing the process lines was asked if he could come up with a solution to the problem. After a couple of years of trial and error, the KBS Long-Radius Tubing Bender was invented and reduced the rejection rate from 40% to less than 10%. For a number of years now, KBS Long-Radius Tubing Benders have been required by all chip plants for contractors installing high-purity process piping.
This system has been approved and used in major micro-electronic facilities and by contractors throughout the United States.

BENDER MARKINGS AND INDICATORS
Springback
With some experience you will be able to predict the amount of springback to expect. Please allow for 1 to 3 degrees of compensation.
Verify the bend angle using a template, protractor or against a known angle to ensure the correct bend angle has been achieved.
Quality Control/Quality Assurance
The rugged heavy-duty, high-quality industrial grade construction of the KBS Long Radius Tubing Benders have been providing users with consistent, precise and repeatable bends for over 30 years.
