Mating Rings

Exceptional seals deserve an exceptional counterpart.

Mating rings and seal runners are a critical half of a face seal assembly. High-precision Qualiseal mating rings and seal runners mate with the face seal assembly to provide optimum performance in the most demanding applications. 

Critical aerospace and military applications rely on the controlled processing and precision of Qualiseal components, particularly in high speed, high temperature and corrosive applications.
