GARDEN GROVE, Calif.—Saint-Gobain S.A.'s OmniSeal spring-energized seals have been qualified for application in various sections of a rotorhead in military helicopters.
The firm said four seals have been qualified for sealing purposes—including sealing the inboard pitch-varying housing, outboard pitch-varying housing, vertical hinge pin and horizontal hinge pin.
The recent qualification acts as a system solution complement to Saint-Gobain's OmniLip lip seals, which perform sealing in helicopter gearboxes.
All four seals were uniquely designed customized to meet key requirements, such as dry running, and are a special type of Saint-Gobain Seals' product family of OmniSeal. The product line is available in multiple designs along with various custom designs.
Saint-Gobain Seals is a business unit under Saint-Gobain Performance Plastics' Engineered Components division.
