Proven expertise in small-bore vacuum insulation

If you’re looking for small diameter vacuum insulation, you’ve come to the right place. We are world-leaders in engineering and manufacturing small, thin, and high-precision vacuum insulated products.

We manufacture a range of Insulon® vacuum jacketed pipes, tubes, hoses, and sleeves in small diameter sizes. Insulon® products can be engineered for both cryogenic and high-temperature applications from -270°C to 1000°C.

Small-Bore Pipe Types and Sizes

Small-bore Insulon pipes are available in straight, rigid, flexible, bend-to-shape, pre-bent, and miniature configurations. We also offer a range of end fittings to integrate with your tube assembly. All Insulon pipes are double-walled and vacuum insulated. Internal diameter (ID) measurements refer to the inner pipe of the double-walled structure.

For Cryogenic and High-Temperature Applications

Engineered for applications from -270°C to 1000°C, Insulon small-bore pipes are suitable for a wide range of applications.

Material Selection

Insulon® small-bore tubing is typically built with stainless steel, Inconel, or other alloys. Be sure to specify any material requirements for your application on your project inquiry form.

We carefully select materials according to the needs of your application. Insulon® products can be designed to meet a variety of material requirements, including:

Stainless steel vacuum insulated pipes
