Parker CPI™/A-LOK® Instrumentation Tube Fittings are designed as leak-free connections for process, power and instrumentation applications. The CPI tube fittings utilize a single ferrule for easy make-up and excellent performance in vibration applications. The “spring loaded” effect of the single ferrule creates a constant tension between the fitting body and fitting nut. The A-LOK two ferrule compression tube fittings are designed to provide reliable leak-free connections for applications that specify a two ferrule system. These single and two ferrule fitting designs are manufactured to the highest quality standards and are available in a broad range of sizes, materials and configurations.
