The 3/4 in. Dura Flo™ Heavy-duty Dripline (0.790 in. ID X 0.940 in. OD) is available with unique spacing configurations and is ideal for commercial applications. This dripperline, also known as emitter tubing, features emitters 1 in. apart grouped in a set of three, with each grouping spaced 6 in. apart. The pressure-compensating 0.5 GPH emitters maintain a constant flow rate even if the water pressure changes. 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.
