Standard flexible tubesProduct catalogCAD drawing

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.


<How to specify models>

For standard flexible tubes, specify tube lengths in addition to models from shape to shape.

When ordering, note that some models have two types of the same size.

The first letter of each model will differ.Conventional product: VF New product: VFP

(Example model) New product (VFP), NW flanged 25A with a length of 500L: VFP1025-500L


* For delivery time and price, feel free to ask us using the standard product estimate request form.
