Ideal for commercial applications, the 3/4 in. Dura Flo™ Heavy-duty Dripline (0.790 in. ID X 0.940 in. OD) offers durability with a flexible design, and available in unique spacing configurations. Also known as emitter tubing, this dripline features emitters 1 in. apart grouped in a set of three, with each grouping spaced 6 in. apart. The pressure-compensating 1.0 GPH emitters maintain a consistent and steady flow rate even if the water pressure varies. The self-cleaning emitters are designed to flush out particles in the water to help prevent clogging. Tubing is made of polyethylene, and emitters are made of polyethylene and silicone, all treated with UV inhibitors.
