:: TECHNOLOGY :: SELF ENERGIZED ::

Taper-lok Seals are self-energized.    The working pressure of the system benefits the sealing integrity acting on the bottom of the seal ring, wedging it against the converging male and female seal surfaces.  Because of this wedging action, the higher the working pressure, the tighter the seal. 

One of the many advantages of a pressure-energized seal is the reduced bolt load required to seal the connection. This not only results in smaller bolts and lighter loads, it also allows the size of the flange to be substantially reduced.  The Taper-Lok© Bolt load is less than an ANSI because the Taper-Lok© gasket is a self energized seal.  With a pressure energized seal the bolt pre load must be equal to the separation loads due internal pressure.  Extra load to seat the seal is not required as with an ANSI.  This reduction in bolt load has the desired effect of reduced bolt size, reduced flange diameter and reduced flange thickness.
