These EPDM rubber air diffusers are incredibly strong and are ideal for pond aeration, circulation and de-stratifying applications
Strong, long lasting EPDM rubber membrane tubular air diffuser.
A Universal air diffuser that is compatible with many brands of air pumps on the market.
Accepts from 1/4" up to 1/2" ID air tubing, depending on diffuser model (see Specs Chart below).
Perfect for pond aeration, circulation and destratification.
Easier to clean and more clog-resistant than air stones.
Available lengths: 4", 6", 8" and 12" long diffusers.
Please Note: 4" and 8" diffusers are available only in Barb connections and 6" and 12" are available in Barbed or Threaded MPT connections.
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
