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

Minimize leaks in your line—these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.

Lighter in weight than their metal counterparts, these quick-disconnect couplings are made of acetal plastic. They are moisture resistant, so they won’t absorb water and lose strength, even in high-humidity environments.

Don’t get your lines crossed—use one of these couplings to quickly connect or disconnect multiple tubes at once.

Prevent mixing the wrong high-pressure lines—these couplings are designed to only connect with a plug or socket of the same color.
