In the S.E.M. (top) the severe effects from over tightening on the sealing surfaces of a legacy face seal fitting are shown.
In the S.E.M. (lower) using Omnisafe torque elimination, the seal area is not galled. One half turn past finger tight is a worst case scenario. At 5/8 turn past finger tight the gasket would be sheared through.
Although Omnisafe can survive this severe over tightening it is not recommended since it will reduce the life on the threads of the male and female nut.
