Galvanized Wide-Radius Elbows
A galvanized 45° elbow is a zinc-coated malleable cast iron fitting with two female-threaded ends that turns a water line by 45 degrees. Thanks to its wide-angle turn, the water flow in the line is interrupted less.
It is used to follow terrain slopes in irrigation lines, to pass beams on sprinkler routes and for offsets made with two elbows. It is supplied in 9 sizes from 3/8″ to 3″.
Main Applications
- Sloped terrain crossings in irrigation lines
- Passing beams and ducts on sprinkler lines
- Parallel line offsets with two 45° elbows
- Smooth turns at tank and booster set outlets
- Low-loss routes in water distribution
- Angled passages in walls and shafts

Which material? Choosing galvanized 45° elbows on galvanized water and irrigation lines keeps corrosion protection equal along the whole route; black 45° elbows are used on black lines.
Advantages

Zinc Protection
- Inner surface at the turn coated against rust
Construction and Design Features
- 45° angle between two Rp female-threaded ends
- Hot-dip zinc-coated inner and outer surface
- One-piece cast body
- TS EN 10242 design A
Send the 45° elbow size and quantity; we will also work out the pipe and nipples needed for the offset.
How to Choose?
- Determine the angleChoose a 45° elbow for smooth transitions and offsets, a 90° elbow for corner turns.
- Measure the sizeDetermine the pipe size in inches; ask for stock above 3″.
- Calculate the offset lengthThe pipe length between two 45° elbows sets how far the line shifts.
- Confirm the mediumUse galvanized fittings on fresh water and irrigation lines.
