We had some 580 fittings factory made to the wrong size. Don't confuse with our 580 fittings......They look the same, but fit 700 and 700 tubing and soaker hose.
Use 700 Coupling to connect 2 pieces of 700 or 710 od poly or soaker hose.
Compression fittings require no glue.
The Black and yellow compression fittings are unique, as besides being compression they also have male hose threads to make them very versatile.
