Chrome Air Divider/Manifold 1/2" Inlet, Various Sizes

These are high-quality chrome air manifolds with a trumpet style design. These air manifolds allow for adjustment of air flow to four or more air stones. Each valve is barbed and can be manually controlled to ensure that equal air flow is provided to each air diffuser or air stone. They are designed to allow excess air pressure from the pump to escape to decrease pressure on the diaphragm of your pump. Each size has a 1/2" inlet to be used with 5/8" tubing and has a 3/16" outlet.
