Tube is a basic crafting material used in multiple fabrication recipes. It is produced in the Fabricator and can be exported to corporate buyers. Tube functions as a mid-tier component for a range of devices and advanced materials.
Tube appears as an ingredient in several crafting recipes across different production buildings. It is required by the Applicator recipe (8 Tube and 2 Glass, produced in the Fabricator in 4 seconds), the Inductor recipe (2 Tube, 1 Wolfram Wire, and 2 Ceramics, produced in the Furnace in 3 seconds), and the Nanofibre recipe (20 Tube and 5 Liquid Helium, produced in the Compounder in 5 seconds). These recipes place Tube at the intersection between basic metal components and higher-tier electronic or material products.
