Saint-Gobain Exhibiting at Paris Air Show, Sharing Its Seals & Polymer Solutions for Jet Engines
Saint-Gobain will be exhibiting at Paris Air Show with its OmniSeal spring-energized seals & rotary lip seals, Ameriseal metal seals, HyComp carbon fiber composite material solutions, Meldin polymer thermoset and Fluoroloy A90 polymer material.

With the recent acquisition of HyComp LLC and American Seal & Engineering companies, leaders in composite and metal sealing technologies respectively, Saint-Gobain Seals has geared itself to be a partner that can meet the needs of many aerospace and space Tier 1s and OEMs, providing not only specific critical parts but also co-engineering to provide a complete system.
Along with the above critical seals and polymer parts that are used for high-temperature needs, their Fluoroloy® A90 material has also been designed to help with this growing challenge. It has been tested in various challenging working conditions and proven to be most suited for the following jet engine (https://www.seals.saint-
Because of this temperature benefit, it is an ideal solution for jet engine lubrication systems where the soak back temperature is sometimes difficult to estimate but does provide between 80 to 100°C more than the permanent working temperature. With a higher performance level (365°C), Fluoroloy® A90 offers better reliability and a superior safety level in comparison to solutions reaching their maximum performance below 300°C and only designed for nominal working temperatures.
The OmniSeal® product line of spring-energized seals is a robust solution in itself, being used in many space applications since the start of the NASA program 60 years ago, e.g., Apollo program, space shuttle program, Mars Rover exploration program and SLS program. Saint-Gobain Seals released a special technical white paper (https://info.seals.saint-
The OmniSeal® rotary PTFE lip seals have also been used as critical parts for many decades in aerospace industry since they are viable alternatives to mechanical or carbon seals solutions when linear shaft speed is above 15 m/s. The lip seals are being used in rotorhead (along with spring-energized seals) and other aerospace applications, including several with linear speed in excess of 90 m/s. Advantages include ease of installation and replacement versus mechanical seals, much less space to be integrated into hardware, and compact design in accessory gearboxes for jet engines but also all accessories connection on turboshaft engines.
