 d. Use of the 90-degree Elbow. On some ships, because of the location
of the discharge risers, the sewage hoses must make bends or changes in direc-
tion in order to reach the pier riser. To prevent kinks in the hose, a special
90-degree elbow can be use in making these changes in direction. The 90-degree
elbow, illustrated in Figure 3-6, is a 4-inch cam-lock, quick connect/discon-
nect, right angle, female/male adapter. If a 180-degree change in direction
is needed, two 90-degree elbows can be connected together.
