Flexible tubes are relatively small-diameter bellows used for piping of equipment that can be bent flexibly.
We are a manufacturer of stainless steel flexible tubes.
- Flexible bending facilitates connection of piping.
- Tube lengths can be easily set.
- Connection of vacuum piping is a standard specification of our flexible tubes.

Since March 2014, we have reviewed the procurement of flexible tubes from the viewpoint of BCP measures. We offer stainless steel flexible tubes that are convenient for piping connection of vacuum equipment and have flexible corrosion resistance,as added new products (10A - 100A) to the four types of conventional standard products.Detailed information.
