Aerospace Sealing Systems

Low firction cantilever finger spring Duruseal® F cantilever finger spring is designed for use in dynamic applications where high deflection and low load is desired.
high load continuous contact spring Duruseal® FC a high load continuous contact spring is an effective face seal.
helical wound spring Duruseal® H a helical wound spring is designed for use in low pressure or vacuum sealing requirements.

Performance Sealing Inc (PSI) designs and manufactures high performance seals for flight critical fluid and mechanical sealing systems. The PSI family of Duron® materials handles a wide range of temperatures -450°F to 600°F (-268°C to 315°C) encountered in cryogenic propellant rocket engine to high temperature gas turbine engine sealing requirements. PSI has a wide selection of spring energizers that allows the seal to be engineered to specific application requirements. Typical gland dimensions for Duruseal® spring energized polymer seals are designed for Mil G-5514G and AS4716.
