Toro - Dripline 5/8 Pc 18" Drp .5 Gph Brown, 500'

Toro PCB Precision Dripline, 1 GPH — 18" emitter spacing with integrated check valves; drains below 2.5 PSI; rated 60 PSI max.
Overview Toro PCB is a 5/8" (0.640" OD) dripline with pressure-compensating emitters at 18" spacing delivering 1 GPH. Factory-installed check valves at each emitter close when pressure drops below 2.5 PSI, preventing line drainage after irrigation cycles on sloped terrain. Maximum operating pressure: 60 PSI. PCB is suitable for turf subsurface drip, shrub bed drip, and sloped residential or commercial applications where low-head drainage would cause uneven watering. The PCB dripline is compatible with standard 17mm drip fittings, Toro AQUA-TRACER end caps, and flushing assemblies. A 120-mesh minimum filter is required upstream. The UV-stable black polyethylene tubing handles exposure during installation and short-term above-grade use. Available in 500 ft rolls. The integrated check valve feature makes PCB particularly well-suited to replace conventional spray zones with drip on sloped sites, eliminating puddle and runoff problems associated with low-head drainage on grades.
