A yellow long-tail elbow is a special 90-degree fitting used especially in sanitary plumbing and natural gas connections, made of brass, with one end externally threaded (male) and the other end internally threaded (female). It takes its name from the yellow color of the brass and the long ("tail") threaded section on one side.
