These double-ferrule instrumentation-grade tube fittings reduce the chance of hazardous and expensive leaks in instrumentation, process, pneumatic, hydraulic, gas and other tubing systems. Each fitting consists of a nut, a back ferrule, a front ferrule, and a body, and when installed with the tubing, becomes a five-piece connection with a solid leak-free joint. The two ferrules are tightly swaged around the tube and the lack of initial strain on the tubing ensures against tube wall damage. Leaks are prevented because there is axial movement along the tube instead of rotary motion creating a joint. This axial movement prevents torque from being transmitted from the fitting to the tubing.
