Lobster back is another name for which piping component?

Double back elbow Elbow Tees Reducers

Correct Answer:

Double back elbow

Explanation:

In piping, some fittings earn nicknames based on their shape. A “lobster back” refers to a double back elbow, a fitting that makes a return turn by two successive bends in a compact space. It's basically two elbows combined to create a tight 180-degree turn, which is why it’s classified with elbows rather than with tees or reducers. A standard elbow is a single bend, a tee adds a branch, and a reducer changes the pipe size. So the lobster back is the double back elbow.
