Edge Welded Metal Bellows & Capsules

SEYMOUR-SHERIDAN, INC. has been manufacturing welded metal bellows for over 40 years. Applications include steam traps, air vents, flexible couplings, valve seals, pressure transducers and vacuum bellows.

Edge welded bellows are custom designed to fit your application. Bellows can be supplied set to free length or evacuated. To accommodate a variety of temperature and pressure environments, bellows can be filled with water or alcohol to achieve specific length and stroke characteristics. Bellows can also be encased and supplied with fittings.
