Parker CPI Instrumentation Tube Fittings are designed as leak free connections for process, power, and instrumentation applications. These single ferrule fittings are manufactured to the highest quality standards.
Parker's Instrumentation Compression Tube Fittings are supplied complete and ready to use. The single ferrule swages onto the tube as it moves down the body seat creating a pressure/vacuum-tight seal on both instrumentation tube and body by the interface pressure and surface finish of mating components.
The CPI™ single ferrule fitting consists of three precision engineered parts designed to provide secure leak-proof joints capable of satisfying high pressure, vacuum and vibration applications. Fittings are supplied complete and ready for use. The front ferrule compresses onto the tube as it moves down the cone of the body creating a pressure/vacuum-tight seal on both tube and body by the interface pressure and surface finish of mating components. The Suparcase® back ferrule then deforms inwards in the cone of the front ferrule, forming into the tube and creating a strong mechanical hold on the tube.
The internal diameter of the body and nut are closely controlled diameters that constrain the tube within a close tolerance of its axis, ensuring accurate alignment within the assembled fitting.
These tube fittings have been specifically designed for use on instrumentation, process and control systems, analyzers and environmental equipment employed in chemical, petroleum, power generating and pulp and paper plants. These tube fittings have also found extensive application in other fields where a high quality tube fitting is required.
