The Stein Seal Company has developed API (American Petroleum Institute) 682 seals for the oil and gas industry market. Stein Seal has designed, manufactured and tested a Type A pusher seal, Arrangement 3, dual pressurized cartridge seal for this market. In an Arrangement 3 design the barrier fluid pressure is kept higher than the seal chamber pressure and is designed to handle and contain hazardous and light hydrocarbon fluids. The process-end face (inner) seal is specially balanced to handle reverse pressures while the atmospheric-end (outer) seal will contain the barrier fluids.

Steins 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
