EZ-Tube vs a rigid nipple: what happens when a pop-up is driven over
EZ-Tube (often called funny pipe, or flexible swing pipe) is a thick-walled, flexible polyethylene tube that connects the lateral pipe to a pop-up sprinkler.
The animation runs the same wheel over two pop-ups side by side: one threaded straight onto the tee with a rigid nipple, one connected with EZ-Tube.

What you’re looking at
- Rigid nipple
- The load goes straight down the nipple into the tee, which can crack and leak underground.
- EZ-Tube
- The tube flexes, the head moves down, and the tee on the lateral is left untouched.
