A seal assembly configured to provide a fluidic seal between openings into objects. A first object is configured to define a first opening that includes a first tapered section tapered from a first start diameter to a first finish diameter. A second object is configured to define a second opening that includes a second tapered section tapered from a second start diameter to a second finish diameter. The assembly includes a straight tube characterized by an outer diameter less than the first start diameter and the second start diameter, and greater than the first finish diameter and the second finish diameter. A fluidic seal is formed when the first object and the second object are forced together with the straight tube therebetween such that the first tapered section and the second tapered section deform the straight tube to form a seal therebetween by radial compression of the straight tube.
