The selection of the most suitable metal seal is a necessary step for ensuring quality and performance under an assortment of different conditions. For any service condition, there's often a delicate balance between load and spring back of the seal. An increase in the load the seal is compressed increases the seal tightness, The springy nature of the seal will also determine how well the tightness is retained, with varying temperatures and pressures.

For a given metal seal cross-section and seal type, it is generally true that with maximum load the spring back is lowest. In general, a seal with the lowest load generated will have the highest spring back.

But there are other factors which affect the performance of a metal seal. These include, for example, the type of flanges and fittings, pressure and temperature cycles, bolt grade, bolt tension and the method to stress the bolts.
