Bellows Seals

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.

• Forms a frictionless secondary seal when used with other seals
• Supplies axial springing for the mechanical seal that allows the bellows to operate over a long axial length
• Pressure balanced under actual design operating pressures to ensure consistent performance
