Applications
Aviation: Spring-Energized Seals Applications
Description
Omniseal® spring-energized seals are used in many core systems of aviation, specifically for aircraft where they handle high temperature and leakage in the jet engines, APUs and control instrumentation. Similar to space launch vehicles, there are hundreds of seals in an airplane. This sealing solution is also used in helicopters along with rotary lip seals.

Jet Engine Lubrication Systems
As manufacturers continue to improve the efficiency of jet engines, this results in the increase of temperatures throughout these systems. One example is High Temperature Stability (HTS) lubrication oils that are conveyed through a complex circuit and subjected to large temperature variations as well as strong vibration. These oils have been developed to sustain the harshest conditions in order to cool down engine parts and lubricate bearings.
