Compression Tubing Coupler
This compression tubing coupler with black insert is used to connect two sections of 1/2" poly tubing with .700" OD.
Often used by irrigation contractors, compression fittings are very economical and do not require clamps or gluing. Because of this, the fittings can be more difficult to install and are not removable/reusable. Compression fittings install over the poly tubing and are size specific for your tubing outside diameter.
