Designed, Engineered & Manufactured in the USA

Flex-A-Seal is a world leader in engineering and manufacturing edge welded metal bellows seals and devices. We offer a complete line of edge 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 metal 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 edge 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. You can review the complete product brochures below by clicking on the low-temperature and high-temperature edge welded bellows images below.
