Black Tubing Vinyl -- 5/8 inch ID, 0.775 OD -- 100' Roll

5/8in Black Vinyl Tubing for Reservoir and Pump Lines Clear tubing on a reservoir line greens up with algae within weeks and starts feeding clogs into the pump. This black tubing shuts that down, blocking light so nothing grows inside the wall. Its food-grade vinyl carries water and nutrient solution safely, in FDA-approved, BPA-free material. At 5/8 inch inner diameter and 0.775 inch outer, it slips onto standard 5/8 barbs and pump ports. A grower then plumbs a clean, dark line that stays clear season after season. Food-Grade Hydroponic Tubing That Bends by Hand The soft wall bends around a reservoir, a bench, or a pump without kinking, so fittings seat by hand. Growers run it for water and nutrient transfer, drain lines, and pump discharge across a hydro build. Made in the USA, it holds up to UV and daily handling on an open bench. A single 100-foot roll plumbs a full room or a multi-tote system in one run. For any line that must stay algae-free and food-safe, it is the black tubing to reach for.
