The Parker CPI 4 PNBZ-SS compression tube fitting is made of 316 stainless steel and connects to tubing on its open end. This cap for closing the end of a pipe or fitting. This fitting is made of 316 stainless steel for higher strength and greater corrosion resistance than 304 stainless steel. Its operating temperatures range from -425 to 1200 degrees F. This fitting has hex nut construction for tighter, leak-free connections.

Pipe and tube fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. Compression fittings do not require tools or sealants, and are useful in installations where a heat source, such as a soldering torch, is prohibited. When purchasing fittings, consider the application, as this will affect material type, shape, size, and required durability. Fittings are available threaded or unthreaded, in many shapes, styles, sizes, and schedules (pipe wall thickness).
