Figure 4. — Illustrations of (A) lip seal placement on the RTCS pMCS device shaft to prevent fluid leak, and (B) test apparatus developed to investigate the relationship of seal leakage rate and the radial interference, material durometer, and seal geometry. Photographs of (C) test mount and lip seal sample, and (D) lip seal test instrument developed and used to quantify leak rate of eight candidate lip seal designs.
