NDS Dripline 1 GPH, Dura-Flo Inline Check Valve, 12" Spacing, 250' - BROWN

NDS Dura-Flo CV Dripline, 1.0 GPH GPH — 12"" emitter spacing; integrated check valves; rated up to 50 PSI.
Overview NDS Dura-Flo CV is a 17mm/18mm dripline with factory-installed check valves delivering 1.0 GPH GPH at 12"" emitter spacing. The check valves prevent line drainage after irrigation cycles, a critical feature for sloped terrain where residual drainage would over-water low-lying areas. Maximum operating pressure: 50 PSI. Dura-Flo CV is suitable for turf subsurface drip, shrub beds, and sloped drip conversions replacing spray heads. Dura-Flo CV connects with standard 17mm drip barb fittings, end caps, and flushing assemblies. Requires 120-mesh minimum filtration. The black UV-stable polyethylene tubing is designed for burial at 4–6" but can be surface-laid under mulch in bed applications. Available in coil lengths suitable for residential and small commercial drip systems.
