Aerospace Seals & Aircraft Sealing Solutions

High-Performance Aerospace Seals

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 aerospace seals and sealing systems for flight-critical applications. As a leading provider of aerospace sealing solutions, we specialize in creating durable fluid and mechanical seals for the most demanding environments.

The PSI family of aerospace polymer seals, made from Duron® materials, handles a wide range of temperatures—from –450°F to 600°F (–268°C to 315°C). This makes our aircraft seals ideal for everything from cryogenic propellant rocket engines to high-temperature gas turbine engines. PSI offers a wide selection of spring energizers that allows the aerospace 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.
