Abstract
A radially compliant and zero net thermal radial taper mechanical face seal. The seal includes a primary seal ring which is radially compliant to the opposing ring due to its narrow ring length, and an opposing ring which has a geometry and physical characteristics such that the thermal rotation caused by itself and the primary ring is zero. The seal includes further design features for enhancing the radial compliance and the zero net thermal rotation characteristics.
