Stein’s design and technical expertise in the manufacture of seals has resulted in a bellows seal with reliable, consistent performance unusual in the industry. Generally paired with face seals, our bellows seals offer outstanding performance in gas or liquid applications characterized by highly toxic, corrosive, high temperature and high-pressure environments. Depending on the application, bellows may be machined, or either hydroformed or welded using Inconel, titanium or 300 stainless steel.
