A single use wall pass-through system having first and second fixed wall parts attached through an opening in a wall, each including a tubular body and a mounting flange for connection to the wall. A connection is located at facing ends of the tubular bodies to allow them to be connected together within the wall that allows adjustability to compensate for the various thicknesses of walls. The fixed wall parts further include clamping flanges used to provide a sealed connection between one or both of the fixed wall parts and the hose or tube which carries the material from an outside area into another area defined on the inside of the wall. A gasket is used here along with a clamp plate for connection to the clamping flange via a clamping ring. The transfer hose and the gasket are disposable. The clamp ring and clamp plate can be re-used.
