Create a watertight connection in your 1/2 in. distribution line using the 1/2 in. Compression Coupling. The coupler is used to connect two sections of 1/2 in. supply tubing or dripline together. No need to stretch the tubing end over the fitting barb—with the compression fitting, simply insert the tubing end inside the compression ring, where an internal barb compresses into the tube to hold it in place. Made for durability, the compression fitting is made of acrylonitrile butadiene styrene (ABS) treated with UV inhibitors to prevent cracking. Drip irrigation systems are easy to customize, install, and operate. As part of a complete system, drip fittings are connectors that attach sections of tubing together or to other drip irrigation parts. Drip irrigation gradually and evenly waters the root zone of your plants, keeping it moist but never saturated with water. Your plants maintain the ideal balance between water and air for optimal growth and overall health. Raindrip is a leading manufacturer of drip and micro-irrigation solutions and the trusted brand of landscapers since 1972.
