Galvanized Elbows
A galvanized elbow is a zinc-coated malleable cast iron fitting with two female-threaded ends that turns a galvanized steel water line by 90 degrees. The inner surface in contact with water at the turn is protected against rust.
It is the most widely used galvanized fitting in water installations, sprinkler and fire lines, irrigation and tank connections. Besides 11 sizes from 1/4″ to 4″, a 5″ option is also available.
Main Applications
- Corner and wall turns in indoor water installations
- Changes of direction in sprinkler and fire hose cabinet lines
- Underground-to-surface transitions in irrigation lines
- Water tank inlet and outlet connections
- Booster set suction and discharge lines
- Cooling tower and process water lines

Which material? In fresh water lines a galvanized elbow maintains the same zinc protection as the pipe; a black elbow is sufficient in closed heating circuits.

How to Choose?
- Measure the pipe sizeBoth ends of the elbow are the same size; add a reducer for a different size.
- Choose the angleUse 90° for corner turns and a 45° elbow for smooth transitions.
- Confirm the mediumChoose galvanized for fresh and fire water, black for closed heating.
- Confirm the large sizeAsk for the pressure rating of 5″ elbows before ordering.
