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

You don't need a clamp to secure these fittings to tubing. They have a nut on the barbed end that tightens to hold the tubing in place.

Not only are these chrome-plated brass couplings corrosion resistant, they’re also durable enough to handle pressures up to 250 psi and can be used with vacuum.

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

Create custom couplings to save space and snake around obstructions. These couplings let you swap in different ends to change the connection size, type, and orientation to fit your specific setup.
