Abstract: A passthrough for a barrier separating a first space from a second space includes a housing mounted to an opening that extends through the barrier. First and second doors selectively block the first and second spaces, respectively, from the opening. First and second upper sealing blocks cooperate with first and second lower sealing blocks, respectively, to define a number of apertures. Each apertures is sized and configured to selectively receive 1) a conduit extending through the corresponding upper and lower sealing blocks and having an exterior surface that sealingly engages aperture, and 2) a plug sized and configured to occlude the aperture.

Abstract: A passthrough for a barrier separating a first space from a second space includes a housing mounted to an opening that extends through the barrier. First and second doors selectively block the first and second spaces, respectively, from the opening. A frame is disposed within the housing and has first and second apertures configured to receive sealing blocks. When the passthrough is in a first state, sealing blocks seal the first and second apertures. When the passthrough is in a second state, a fluid conduit passes through the first and second apertures and sealing blocks seal the space between the first and second apertures, respectively, and the conduit.
