*Reactor Pressure Vessel
HELICOFLEX®
HELICOFLEX

The sealing principle of the HELICOFLEX® family of seals is based upon the plastic deformation of a jacket of greater ductility than the flange materials. The combination of elasticity and plasticity makes the HELICOFLEX® seal the best overall performing seal in the industry.

O-FLEX™
O-FLEX

O-FLEX™ Metal O-Rings are designed to provide a sealing option for high pressure/temperature applications that require minimal spring back. The O-FLEX™ is made from high strength metal tubing that is coiled, cut and welded to size.

CEFIL'AIR<sup>®</sup> Inflatable Seals

CEFIL'AIR® Inflatable Seals

*Pool goes in reactor building and fuel building

When faced with the problem of sealing between parts which move in relation to one another and capable of being connected and disconnected at will, the easiest, safest and most effective technique is to use pneumatic seals.  CEFIL'AIR® seals have been designed to meet these multiple applications.

ORIGRAF®
ORIGRAF®

Unlike flexible graphite cut gaskets, the compression of the ORIGRAF® die-formed seal is limited by a mechanical stop: groove or inner and/or outer ring. In the case of assemblies subject to extreme pressure and/or temperature this design prevents application of an excessive seating stress on the seal during transients.
