Male Hosetail to fit Soaker hose - Rigid plastic 16mm barbed fitting. The barbed side pushes in to the Soaker Hose and the other 3/4" diameter male threaded end screws into the Tap Adaptor which in turn pushes as a click fit into a standard hose pipe extension or tap connector. Dip the end of the Soaker Hose into some hot water, then push the barbed fitting firmly into place. This forms a good water tight seal.
