Setting up an automatic watering system for your chickens, ducks, or rabbits? These Aopchry PVC tee fittings are essential connectors. This pack gives you 20 fittings, which is great for larger coops or complex piping. They're made from thickened, high-quality white PVC, so they're much more durable than cheap, thin plastic – less likely to crack or break. The design is a reducing tee: 1/2 inch Slip on two ends and 1/8 inch Female Pipe Thread (FPT) on the branch. The threaded connection on the 1/8\ port is key – it screws onto things like water nipples or cups tightly, dramatically reducing the chance of leaks (no more soggy coop floors!). Installation is super easy; no drilling needed. They're compatible with vertical nipples, horizontal nipples, chicken waterer cups, and other small animal watering systems. Easy to clean for healthy drinking water. A reliable, simple part that makes DIY poultry plumbing a whole lot easier and cleaner.
