16mm-4mm air line connector.

The 16mm - 4mm air line connector is a heavy-duty reducing tee that allows you to connect 16mm silver air line pipe from your air pump into 4mm piping that will run into your pots. The air line connector is used in our RDWC, AERO & RAIN systems and can be used with 4mm pink or 4mm green pipe and 16mm silver or 16mm green pipe if you need it to.
