This Anderson Metals 00397 anchor coupler is a 1.31" long brass pipe fitting with 3/8" female NPT threads. The anchor coupler connects two pipes of different diameters going in the same direction to extend a straight run. It has female National Pipe Taper (NPT) threads for connecting to male threaded pipes, creating a tighter seal than straight threads. This fitting is made of brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. Brass can be connected to copper, brass, plastic, aluminum, and welded steel. This fitting has an operating temperature range of -65 to + 250 degrees F. The anchor coupler has fair vibration resistance and is suitable in low to medium pressure applications.

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

Anderson Metals manufactures brass fittings, valves, and pipe nipples. The company, founded in 1951, is headquartered in Kansas City, MO.
