Flex-A-Seal is a world leader in welded bellows engineering and globally-renowned manufacturer of welded metal bellows seals and devices. We offer a complete line of welded metal bellows seals for both standard and high temperature applications. Flex-A-Seal also specializes in cryogenic bellows seals as well as specially engineered bellow devices for vacuum applications. Our standard welded bellows seals can operate in conditions up to 400° F, while our high temperature bellows seals can support temperatures of up to 800° F. Our welded metal bellows cover a wide spectrum of applications by easily converting metallurgy from AM350 bellows to Hastelloy® C276 bellows in lower temperature service, or from heat treated AM350 bellows to heat treated Alloy 718 bellows for high temperature applications.
