There are many instances when more than 1 or multiple air stones/ diffusers are desirable in a fish pond, koi pond, and/or water garden. These Pond Air Pump Manifold Air Line Diffusers are the key. Each one has a valve for each air line so airflow to every air stone deployed can be independantly adjusted. Constructed of stainless steel, these Pond Air Pump Manifold Air Line Diffusers can be used outdoors and will provide years of rust free service.
These particular air pump manifolds can be used with many air pumps. Most air pumps come with a small piece of hose to transition from the air pump to the manifold. If not, 11/16 tubing will be needed to attach the manifold to the manifold.
Each tap fits standard air line; 3/16" - 1/4"
