Rubber Poly Diffuser Tubing
Aeration » Air Diffusers »
This rugged rubber/polyethylene diffuser hose can take punishment. It springs right back even when walked on! The pressure resistance is approximately 4 psi (110" H2O), allowing a diffuser length of up to 30' per inlet. It is not compatible with regenerative blowers.
Hold-downs or weights are required to counteract buoyancy. The gas flow rates shown are only an average. Much higher and lower flows are possible. It’s made with a special process to produce fine bubbles, making it a low-cost choice for diffusing pure oxygen. The lower cost 1/2" OD10 is a fine-pore diffuser, but produces somewhat larger and less uniform bubbles than the 1/4" OD4. It can be used with 3/8" barb fittings with clamps. Both are black. Hose ends may be heat sealed. OD10F and OD4 are sold by the foot, OD10R is a 100' roll. Made in USA.
