8" Rubber Membrane Air Diffuser w/ 1/2" MPTProduct Code: RAD850
These EPDM rubber air diffusers are incredibly strong and very easy to clean. In testing, they produce a slightly larger air bubble than air stones or other diffusers, which means less oxygen transfer into the water. But their low cost and effortless setup makes them a terrific choice if you are simply trying to circulate or destratify pond water. Diffusers have 1/2" MPT connection. Use our FA38 brass adapter to attach to 3/8" airline.
