Metal hose fittings have better durability than plastic barbed hose fittings.

Fittings are metal for better durability than plastic barbed hose fittings. They have sharper barbs than standard barbed hose fittings to grip push-on hose without the need for clamps or ferrules. The more you pull on the fittings, the tighter the hose will grip.

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 hose and secure with a clamp or a crimp-on hose ferrule.

The female connector screws directly onto the hose without the need for a separate adapter. When assembled, the fitting compresses against the hose, forming a strong seal. Also known as reusable fittings, they can be unscrewed from the hose end and used on a new hose.
