Actiseal-C, Actiseal-E

The ACTISEAL-C and ACTISEAL-E are elastic gaskets which have the equivalent composition and temperature/pressure characteristics to the metal O-ring, yet achieve high spring characteristics and low load characteristic due to the special structure design and enhance the function to keep sealing flexibly and tightly in case of a flange distortion. These seals demonstrate stable sealing performance under extremely low temperature, high temperature and high pressure conditions.


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 [1,38×109 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.

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 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.
