High quality, flexible 1/2" blank distribution tubing used to run water to landscaped areas to connect 1/2” Emitter Tubing, or tapped into with 1/4" fittings for use with micro-watering devices. Designed for clog-resistant flow and connects easily to your faucet, garden hose or existing underground sprinkler head (using Rain Bird kits sold separately: FCKIT-1PK, EF075FHTS, RCKIT-1PS). Professional-grade features include extra flexibility for kink-free installation, plus unmatched resistance to chemicals, algae growth and UV damage. Tubing is easy to unroll and stake in gardens, flower beds, ground cover or other landscaped areas. Industry leading flexibility allows tighter turns with fewer elbows for fast, easy installation. Perfect for small, narrow and tight planting areas, as well as areas with tight curves or many switchbacks. Designed for underground or above-ground installation. Unique Micro-Porous design creates an ultra-tight connection; tubing expands over fittings then shrinks making it almost impossible to remove without cutting. Unique compact coiling method allows tubing to remain coiled as its extracted making it easy to use, store and eliminates waste. Just cut, place and connect in any arrangement using Rain Bird 1/2" universal barbed or Easy Fit compression fittings and stakes (sold separately).
