Rain Bird's 1/4 in emitter tubing waters plants uniformly with pre-installed, pressure compensating emitters spaced every 6 in. The emitters are designed for clog-resistant flow at 0.8 gph (gallons per hour) to ensure even, reliable watering. Just cut, place and connect in any arrangement using Rain Bird 1/4 in barbed fittings and stakes (purchased separately). Flexible 1/4 in emitter tubing is ideal for extending watering to narrow planting areas and container plants. Constructed of UV-resistant polyethylene resin materials giving it the flexibility of vinyl with the hold of poly. Unique micro-porous design creates an ultra-tight connection, tubing expands over fittings and shrinks making it almost impossible to remove without cutting. Professional-grade features include extra flexibility for kink-free installation, plus unmatched resistance to chemicals, algae growth and UV damage. For installations at or below grade.
