Water your plants with a steady flow of water along the along the entire line with the 1/2 in. Drip-A-Long Dripline. Durable tubing comes preassembled with 1 GPH pressure-compensating (PC) emitters inside, spaced 18 in. apart. PC emitters maintain the same output of water even when the water pressure varies, and at any position along the length of tubing. The emitters have a turbulent flow design which flushes out sediments that can lead to clogging. This dripline, also known as dripperline, uses the industry standard tubing size of 0.520 in. internal diameter (ID) X 0.620 in. outside diameter (OD). Tubing is made of polyethylene treated with UV inhibitors, and the emitters are made of polyethylene and silicone. Drip irrigation systems are easy to customize, install, and operate. As part of a complete system, the dripline delivers water along the entire line; pressure-compensating emitters maintain a constant flow rate at varying water pressures and location along tubing.
