The SMC KA series 90-degree elbow fitting is made of brass and has tube and UNI male connectors. This 90-degree elbow fitting, or "ell," connects two pipes at a 90-degree angle to change the direction of flow between pipes. It is a push-to-connect fitting that connects to pipes or tubing on one end and has a Universal (UNI) male connector on the other. The 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. The working pressure for this fitting is up to 145 pounds per square inch (psi), and its operating temperature ranges from 0 to 40 degrees C.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).SMC Corporation manufactures actuators, valves, airline equipment, connector fittings, electrical products, vacuum products, dryers, temperature control chillers, and accessories. SMC Corporation of America is headquartered in Noblesville, IN, and meets International Organization for Standardization (ISO) 9000:2000 standards.
