Tight-Seal Barbed Hose Fittings for Air and Water

*Also known as ball-seat hose nipples, these fittings consist of a barbed shaft with a rounded end that sits inside a female threaded nut. When mated with a male threaded fitting, the rounded end presses tightly against the inside of the male threads for a better seal than a single-piece fitting. Once assembled, insert the barbed end into rubber hose and secure with a clamp or a crimp-on hose ferrule. The nut swivels until tightened for easy installation. Fittings are brass for good corrosion resistance.
