Circumferential Seals

Stein Seal's line of precision crafted circumferential seals are perfect for low-pressure applications where minimal, controlled gas leakage, high temperatures, unlimited axial shaft movement and low wear are critical. They can be used independently or as part of a sealing system. The exceptionally lightweight carbon material and split housing capability make it easy to install, remove or repair seals in limited space areas.

• aircraft engine main shafts and accessory gearboxes
• recirculation pumps
• process industry
• propulsion systems

Configurations include standard single ring, back-to-back, face-to-face, or a tandem arrangement.

• Unique design increases flexibility to provide better sealing
• Special gap segments permit the seal to adjust dimensionally for minimal leakage
• Distinctive fabrication reduces pressure loading to maximize seal life
• The use of compression and garter springs ensures that the segments remain in contact with mating surfaces during low delta pressure and shutdown conditions
