Rain Bird’s copper-colored XFS Dripline with Copper Shield™ for sub-surface drip irrigation is the latest innovation in the Rain Bird Xerigation® Family. Rain Bird’s patent-pending Copper Shield Technology protects the emitter from root intrusion, creating a long-lasting, low maintenance sub-surface drip irrigation system for use under turf grass or shrub and groundcover areas. Having the copper color outside ensures the copper chip is inside and that your dripline is protected from root intrusion. XFS Dripline with Copper Shield is perfect for small, narrow and tight planting areas, as well as areas with tight curves or many switchbacks. It accepts Rain Bird Easy Fit Compression Fittings, XFF Barbed Insert Fittings and other 17 mm barbed insert fittings. XFS Sub-Surface Dripline - 0.9 GPH, 18 in. Spacing, 500 ft.
