Seal for high vacuum quick disconnect
For this space station application, leakage control was absolutely vital. The vacuum and pressure combined with the temperature range and gland design made this application challenging.
Custom Turcon® Variseal® W2 with a Polymonochlorotrifluoroethylene (PCTFE) jacket and a heavy-load Slantcoil® spring
As difficult as the operating conditions were, the solution was rather simple. The specified seal was a Turcon® Variseal® W2 machined at a 45° angle. With the proper choices of jacket material and spring load this seal provided both the reliability and sealability required for use in the space station.
