Dahszhi 5Pcs Aquarium Plastic 6-Way Outlet Air Flow Pump Tubing Splitter Control Valve White-G6.7

One of the outputs was bent and cracked on one piece. There are flimsy end caps that were not watertight. I had to silicone them now they seem OK.

This probably works rather well for what it was intended. I use it for breathing oxygen in multiple location.

Currently being used to split the output of a small water pump to individual net pots for seed germination. Works perfectly for my needs, no leaks.
