An overview of metal bellows sealing. 12-10 Metal bellows seals perform many functions. Unfortunately all the functions are not available in the same seal.
Most solvents present a real problem for elastomer selection.
You would be better off if you could eliminate these special materials all together Metal bellows are also used to eliminate elastomers because of temperature limits. All elastomers have both an upper and lower temperature limit that prevents them from sealing many hot resins, polymers and cryogenic applications. This is the most popular type used in mechanical seals. End fittings are welded to the bellows to hold the seal faces, sleeve and gland attachments. The bellows can be formed by forcing a metal tube into a die.
