The Parker CPI tube fitting is designed as a leak-free connection for process and instrumentation applications. The CPI tube fitting offers a single ferrule design that requires only two metal-to-metal seal points to affect a leak-tight seal. With fewer components, the CPI tube fitting design reduces potential leak paths. Available in brass, steel, stainless steel, and other alloys, the CPI tube fitting seals equally well on both thin and heavy wall metal tubing. 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.
