Thread Content
An O‑Ring Face Seal Tube Fitting will be used to charge the domed section of the vessel with Nitrogen gas. The receiving nozzle for this fitting is to be located within the domed section of the vessel. The female thread for this nozzle is a 1/2‐20 UNF‐2B thread. How should this sentence be translated appropriately? I also don’t understand what 1/2-20 UNF-2B thread means
Let me give it a try: the dome-shaped chamber is sealed with O-ring seals, filled with nitrogen, and the receiving port is located inside the dome-shaped chamber. The specifications for this female threaded receiving socket are 1/2‐20 UNF‐2B. :)
