This 1/2" I.D. weighted diffuser tubing is useful in applications where long lengths are required. Equal bubble distribution is possible with lengths as long as 200'. On the WD55 ice-melting diffuser tubing, single die cuts are located every 24".
This weighted tubing requires WD fittings. Full rolls are 250' long (60 meters). This diffuser tubing is not compatible with most regenerative blowers as 2–5 psi is required. Also note that this coarse bubble diffuser tubing will only provide about 1/3 as much oxygen transfer per cfm of air as Sweetwater® diffusers.
Note: Diffusers are also known as airstones. Tubing is also known as hose.
