Midland brass fittings are popular because they are strong and durable and hence widely used in industrial and residential applications. The use of brass to make various fittings provides a distinct look because of its yellow color. The advantages of brass for fittings include its good corrosive resistance, and also its plating, joining, polishing and finishing characteristics. Brass as a material is easily machined and hence can be given any shapes of the various types of fittings available. Midland Metal brass fittings are available in both leaded and lead-free brass.
