What is Instrumentation Tube Fitting?
Instrumentation tube fittings are specialized compression tube fittings used to connect instrumentation tubes and pipelines in fluid or gas systems. These fittings create secure and leak-tight joints using a double ferrule compression mechanism that grips the tubing firmly. Commonly used in instrumentation pipe fittings, they ensure reliable performance in high-pressure and precision measurement systems, including installations with pressure gauge pipe fittings and other critical instrumentation components.
