16mm-4mm air line connector.

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