hose insulation

Chiller Hoses

Hose insulation prevents condensation and keeps the surface temperature of the hose close to ambient, regardless of media temperature. At a semiconductor fab, condensation can be a major issue because of the volatile and highly dangerous fluids used in the chip manufacturing process. Every drip/leak that is detected can be viewed as a possible hazardous fluid, causing the tool or fab to be shut down for safety reasons. In other low temperature applications (such as Joule-Thompson effect with pressure drop), insulated hose will reduce or eliminate ice build-up on the outside of fluid system components, which can affect their performance.

Swagelok insulated hoses minimize heat loss over the length of the hose and keep the media temperature stable and consistent from beginning to end. A lack of insulation will require higher levels of cooling energy and affect the temperature stability at the semiconductor fab tool.


  • Maintains system flexibility and thermal consistency with compact aerogel material
  • Minimizes water vapor ingression from ends with silicone end seal
  • Eases routing and saves space with the smaller outside diameter provided by compact material
  • Allows for easy identification of hose type (e.g., supply vs. return) with color-coded external wrap over the insulation
  • Covers a majority of applications with hose sizes from 3/8 in. to 1 in. (9.6 mm to 25.4 mm)
