What is the difference between a 90-degree elbow and a 45-degree elbow?

Explanation:
Elbows change the direction of a pipe run. The main difference between a 90-degree elbow and a 45-degree elbow is the bend angle. A 90-degree elbow makes a right-angle turn, a full quarter turn, while a 45-degree elbow makes a gentler turn by 45 degrees. Material or color code are separate attributes and don’t define the bend; the radius of the bend can vary independently, but the defining feature here is how much the pipe turns.
