Step on it—it springs right back! This is efficient tubing, with a pressure 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. \u003c\/p\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cp\u003eNo warranty due to individual clogging and fouling possibilities.\u003c\/p\u003e\n\u003cp\u003eSold by the linear foot\u003c\/p\u003e","brand":"Dynamic Aqua-Supply","offers":[{"title":"Default Title","offer_id":45543930331267,"sku":"OD2F","price":4.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/2593\/8322\/products\/OD2R.jpeg?v=1540240496","url":"https:\/\/dynamicaquasupply.com\/en-us\/products\/od2r-high-efficiency-diffuser-tubing-linear-foot","provider":"Dynamic  Aqua-Supply","version":"1.0","type":"link"}
