CPI™ Couplings

Parker CPI™ are single-clamp ring pipe couplings designed for secure and leak-tight connections in instrumentation, process, and control systems. The Suparcase®-treated clamping ring provides a strong mechanical grip and good resistance to vibrations. The fittings are suitable for high-pressure and vacuum applications and are supplied fully assembled. They are available in several sizes and configurations.
