Rain Bird XFS0618500 is subsurface dripline with Copper Shield technology to protect its emitters from root intrusion. Factory-installed, pressure-compensating emitters deliver a nominal 0.6 gallons per hour each at 18-inch intervals. The 500 ft. copper-colored coil is intended for designed irrigation layouts beneath turf, shrubs and groundcover.
Key Features
Built-in 0.6 GPH emitters at 18-inch spacing.
Copper Shield technology protects emitters from root intrusion.
Pressure-compensating emitters operate within an 8.5–60 PSI range.
Copper-over-black tubing works with XF insert, Easy Fit compression and suitable 17 mm insert fittings.
Common Uses
Subsurface irrigation beneath turfgrass.
Buried dripline layouts in shrub and groundcover beds.
Repairs or extensions where the existing zone requires 0.6 GPH flow and 18-inch emitter spacing.
Select row spacing and burial depth for the soil, root zone and site conditions using the XF system guide. Use 120-mesh filtration, pressure control suited to the zone, accessible flush points and air/vacuum relief at system high points as specified for XFS. Check the XFS lateral-length table; a 500 ft. coil is not a guarantee that one 500 ft. lateral will operate correctly. Copper Shield root protection does not replace filter cleaning or flushing. Fittings and control-zone components are separate.
Frequently Asked Questions
Is this ordinary blank tubing?
No. XFS contains built-in pressure-compensating emitters and Copper Shield root-intrusion protection for subsurface irrigation.
What does 18-inch spacing describe?
It is the distance between emitters inside the tubing. Row spacing between separate laterals must be selected for the soil and planting layout.
Does Copper Shield eliminate system maintenance?
No. It protects emitters from root intrusion, but the system still needs appropriate filtration, flushing and routine inspection.
Why Buy from Big Frog Supply?
Choose XFS0618500 when your subsurface layout specifies 0.6 GPH emitters every 18 inches. It combines Copper Shield root-intrusion protection with fewer emitter locations per foot than the 12-inch version, so confirm soil wetting and row spacing before choosing it for a turf or groundcover zone.
