Product Code: OD2R This patented, low-pressure rubber/polyethylene diffuser hose is made for aquaculture. Step on it—it springs right back! This is efficient tubing, with a pressur e resistance of only 12" of H2O at normal flowrates when new. Diffuser lengths of up to 20' per inlet are possible at low airflow rates. Tubing has a good oxygen transfer rate and is compatible with both regenerative blowers and linear air pumps. The gas flowrate is an average of .1–.5 cfm/ft; higher and lower flows are possible. Tubing produces a strong volume of medium-size bubbles (approximately 3 mm). For connections, use 1/2" barb fittings with clamps. Hose ends may be heat-sealed or fitted with a plug and clamp. To counteract buoyancy, hold-downs or weights are required. For best results, the tubing should be oriented with the blue stripe on the bottom. Inside diameter is 1/2" (13 mm); outside diameter is 1" (25 mm). Made in the USA by Colorite Plastics. No warranty due to individual clogging and fouling possibilities. 100 Foot Roll Show more
