With this T fitting, you can easily split the 16-17mm double layer tubing into two routes. The tubing, in turn, will act as a delivery line that either feed the pots via the micro dripper assembly or this pipe attaches to the bubbler (via the 3/4″ male adapter) which then feeds the pots via attached green dripper lines

The white outer layer helps to deflect light and keep the temperature in the hose cooler, the opaque black inner layer blocks all light, preventing algae build-up in the hose and keeping the system clean.
