20 Pack - 5/8" (17mm) Drip Tape Tee Fitting - Works Great with and is Compatible with Irretec P1 Ultra, Rivulis T-Tape, Aqua-Traxx, Irritec, Chapin, and 5/8 inch Netafim Streamline

These work very well for flat line and hard tubing. I was very surprised they don't leak at all. Lightweight, but they're not being moved or hit. They do not seem to be UV protected so i doubt they'll last more then a single season. Time will tell. For the cost, replacement is still cheaper than other brands.

work as expected
