Rubber Membrane Air Diffuser - 12" With 1/2" Barb

These EPDM rubber air diffusers are incredibly strong and are ideal for pond aeration, circulation and dissatisfying applications.

Features:

• Unlike air stones these diffusers are easy to clean
• In testing they produce a slightly larger air bubble than air stones which translates into less oxygen transfer into the water, so for fish holding tanks, raceways, fish production ponds, etc. we recommend air stones
• Barbed inlets have multiple size barbs, simply cut to fit the size tubing you are using
• An excellent choice for pond and water garden aeration since they actually produce more circulation and water movement

• Dimensions 1 1/2" diameter 12" long
• Inlet 1/2" npt
