Custom Indium Gaskets and Seals for Cryogenic Equipment

Cryogenic Application

Custom Gasket Mfg. specializes in the manufacturing of die-cut and water jet cut indium foil gaskets and seals and pre-cut indium gasket sets primarily for the cryogenic equipment industry. Indium is a flexible silver metal that can be utilized to seal unsolderable surfaces in cryogenic applications. Gaskets that are made from other materials only form a physical barrier to the medium being contained. When indium is used, a mechanical and chemical bond are also formed between the two surfaces being joined. Indium is perfect for the cryogenic industry since it is far less sensitive to the effect of low temperatures, mechanical shocks, and vibrations than seals of other materials. Due to its softness, indium is considered an ideal material to create a full compression seal. Custom Gasket Mfg. cuts indium into a variety of custom shapes including flat gaskets, seals, washers, discs and rectangles.
