Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

Color-code fittings for easy identification. These aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

Made of stainless steel, these fittings have better corrosion resistance than brass fittings.

Made of brass, these fittings resist corrosion from water and are more durable than plastic and aluminum fittings.

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