A seal is a device which prevents the passage, flow, or leakage of a gas or fluid. Static sealing takes place between surfaces which have little or no movement relative to one another. Our metallic seals provide robust seal integrity to many demanding sealing problems in a variety of industries. Millions have been supplied to solve leakage problems while providing benefits to our customers.
EEA STATIC SEALS Solving demanding sealing problems is the driving force of Eagle Engineering Aerospace. We have provided reliable, lab-tested, and field-proven performance capabilities in critical sealing applications as diverse as cryogenic, hard vacuums, ultraclean systems, leakage control to the extreme limit and severe flange deflections. C-SEALS To transition from an "O" ring to a "C" shape, the hoop restraint of the seal was greatly reduced. The C-seal was designed to fit the cavity loosely at installation, but tightly at assembly, or "bolt-up". Once the closed side of the seal is butted up against the rigid surface of the cavity, the hoop stress is essentially fixed, thus allowing an increase in pressure without an increase in hoop stress through the cross-section. # Excellent for "rigid" connections where little or no axial deflection occurs. # Low leakage rates - can be enhanced by plating. # Ultra high vacuum (10-10 Torr) to high pressure (200,000 psi [1,38x109 Pa]) applications. # Compression load in the range of 100 to 1000 pounds per circumferential inch of seal (PCI) [178 to 175 N/mmCirc] are available on requests. E-SEALS The E-seal shape was created to meet the needs of high-pressure pulsations and large cavity deflections. It is used to seal cavities that have axial and some small radial deflections. The E-seal's relatively low compression load renders it not as well-suited for plating as a C-seal. Available in two basic orientations, the E-seal offers a flexible cost-effective, and reliable design. Flexible, suitable for applications with cyclic axial deflection # Excellent springback and reusability characteristics # Compression in the range of 10 to 50 pounds per circumferential inch of seal (PCI) [2 to 9 N/mmCirc] NAFLEX-SEALS Naflex seal is the state-of-the-art computer-aided design and manufacturing engineering, including finite element modeling and analysis and parametric modeling. Naflex seals are designed to have infinite operational life. Exceptions to this would occur with seals operating under excessively extreme condition, specially related to temperature, and vibration.
