The double-ferrule adapter fitting is made of stainless steel and has tube and NPT female connectors. This adapter fitting connects pipes or fittings with different end types, diameters, or materials. It is a push-to-connect fitting that connects to pipes or tubing on one end and has a National Pipe Taper (NPT) female connector on the other. The fitting is made of stainless steel for resistance to scaling and corrosion. It has a double ferrule construction, reducing the possibility of leakage.

Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries. Push-to-connect 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 pipe 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).
