About Us

Since 1997 Indium wire Extrusion has been available to recommend flange design and seal wire sizes.

experience you can trust

Indium Wire Extrusion was originally organized in 1997 to work with small University research groups to offer a new service of recycling indium cryogenic o-ring seals at a significant financial advantage over new wire seals saving fifty percent in cost.

Our expertise comes from 35 years of experience in cryogenics and development of very large low temperature liquid helium cryostats to cool 3000 pound gravitational wave detectors to four Kelvin.

We offer an understanding and engineering advise of flange design and wire size seal selection for your project. Our chart will guide you to proper seal groove design as a function of flange diameter. In addition, you can call us to discuss your special design needs. We also have INDIUM WASHERS in the standard 3.37″ diameter for Cryocooler Cold Heads.

We can talk cryogenics and vacuum technology to help guide your design. These principles apply to the Medical field, Aerospace, or Research and Development. Indium wire metal seals made by IWE DO NOT outgas or have permeation problems of rubber o-rings. Our seals will provide a vacuum tight bond down to near absolute zero with assured success of reaching ultra high vacuum if required.
