Abstract: Disclosed is a system and method for sealing an opening through the boundary of a controlled thermal and gaseous environment such as an incubator or refrigerator, where conduit channels of arbitrary size and number are transferred across the boundary. A silicone or polymeric tube with flanges at either end is passed through the boundary opening, fixing one side to the boundary wall and attaching the other to a mechanism that controls or constrains the rotation of the tube. This is achieved by rotating or twisting one end of the tube, creating a hyperboloid-like structure that will seal around the conduits and thereby seal the opening. To further improve thermal efficiency, insulating material such as expanded polystyrene beads are placed into the space between the silicone or polymeric tube and the wall of the incubator, providing thermal stability that cannot be achieved by conventional conduit transferring methods.

Abstract: A metal O-ring is provided. The metal O-ring has a sidewall with an outer surface and an inner surface. The outer surface of the sidewall is machined to selectively thinning the thickness of the sidewall, such that the sidewall of the of the metal O-ring has a plurality of thicknesses equal to or less than a maximum thickness and equal to or more than a minimum thickness. Selectively thinning the sidewall by machining the outer surface allows for control of the elasticity of the metal O-ring. Controlling the elasticity of the metal O-ring, and potentially increasing the spring back, may provide for increased contract pressure at a sealing interface, which would facilitate sealing. The machined outer surface of the metal O-ring are generally machined to flat surfaces.
