Heavy, sturdy 3-way valves. Note that all 3 ways are male and they are 1/2".There is no any rubber sealant of any kind come with. Be sure to use some PTFE tape for better preventing leakage.There is no certification or claims of any kind, so unsure it can be used for drinking water or not. Use at your own risk. It fits my application where it's for connecting garden irrigation system only.Overall, solid build.
