A single use wall pass-through system having a fixed wall part attached through an opening in a wall and connected by at least one mounting flange. The fixed wall part includes clamping flanges used to provide a sealed connection between the fixed wall part 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 along with a clamp plate for connection to the clamping flange via a clamping ring. The clamp plate can be two pieces separated by a dividing line and the clamp plate hose opening intersects the dividing line. The transfer hose and the gasket are disposable. The clamp ring and clamp plate can be re-used.

1. A single use wall pass-through system, comprising a tube assembly that is attachable through an opening in a wall, including a tubular body with at least one support flange,a first mounting flange connected to the support flange around an inner periphery of the first mounting flange and adapted to be connected to the wall around an outer periphery thereof that overlaps the opening,the tube assembly includes a clamping flange connected to each end of the tubular body,a hose or tube is arranged through the tubular body and passes through a hose opening in a gasket,a clamp ring that clamps the gasket between one of the clamping flanges and a clamp plate,the clamp plate is provided as two clamp plate pieces that are aligned together about a dividing line to form the clamp plate, and a clamp plate hose opening for the hose or tube intersects the dividing line, andthe tube or hose and the gasket are single use. 2. The system of claim 1, wherein the clamp ring includes two half-rings that are connectable to one another, and the clamp plate pieces are fixed to respective ones of the half-rings. 3. The system of claim 1, wherein there are first and second ones of the support flanges on the tubular body, and a second mounting flange connects the second support flange to an opposite side of the wall from the first mounting flange. 4. The system of claim 3, wherein the mounting flanges include a wall mounting surface and a support flange mounting surface, and the wall mounting surface is axially offset from the support flange mounting surface. 5. The system of claim 4, wherein the axial offset is determined by a wall thickness and a distance between the first and second support flanges. 6. The system of claim 4, wherein the wall mounting flange surfaces are sealed to the wall and the support flange mounting surfaces are sealed to the support flanges. 7. The system of claim 1, wherein there are a plurality of the clamp plate hose openings in the clamp plate, and each of the clamp plate hose openings intersects the dividing line. 8. The system of claim 1, wherein the clamp plate hose opening is larger than an outside diameter of the hose or tube. 9. The system of claim 1, wherein the clamp plate hose opening includes a tube engaging profile on an inner surface thereof. 10. The system of claim 9, wherein the hose or tube fits in the clamp plate hose opening with an interference fit. 11. The system of claim 10, wherein the tube engaging profile is a convex surface. 12. The system of claim 10, wherein the tube engaging profile is a beveled surface. 13. The system of claim 1, wherein the hose or tube is made of silicone or a thermoplastic material the gasket is made from silicone or a thermoplastic material, and is connected to the hose using silicone or an adhesive of chemical bond. 14. The system of claim 1, wherein a plurality of the hose openings are located in the gasket, and a corresponding plurality of the hoses or tubes are provided, with one of the hoses or tubes extending through each of the openings. 15. A method of connecting a hose through a single-use wall pass-through system, comprising: removing a clamp plate installed on a clean side of a wall pass-through chamber defined by a tubular body connected to clamping flanges that are attached on either side of a wall through an opening between the clean side and a dirty side, with the body being connected to the wall in a sealed manner;installing the tube through a hole or opening in a gasket on the clean side, such that the tube is connected to the clean side gasket in a sealed manner;placing an end of the tube which is closed off into an inside of the wall pass-through chamber;re-installing the clean side clamp plate over the gasket on the tube on the clean side so that the end of the tube is sealed in the chamber;pressurizing the chamber with process air from a process air source;removing a clamp plate from the dirty side;pulling the tube into the dirty side;installing the tube through a hole or opening in a gasket on the dirty side such that the tube is connected to the dirty side gasket in a sealed manner gasket;re-installing the dirty side clamp plate over the gasket on the tube on the dirty side so that the end of the tube extends out through the dirty side gasket. 16. The method of claim 15, wherein the clean side clamp plate is provided as two clamp plate pieces that are aligned together about a dividing line to form the clamp plate, and a clamp plate hose opening for the hose or tube intersects the dividing line, and the two clamp plate pieces are placed around the hose or tube during the re-installing of the clean side clamp plate. 17. The method of claim 16, wherein clamp plate hose opening includes a tube engaging profile on an inner surface thereof that clamps against the hose or tube. 18. The method of claim 15, wherein the dirty side clamp plate is provided as two clamp plate pieces that are aligned together about a dividing line to form the clamp plate, and a clamp plate hose opening for the hose or tube intersects the dividing line, and the two clamp plate pieces are placed around the hose or tube during the re-installing of the dirty side clamp plate.
