Get precision watering right along your distribution tubing with the 1/2 GPH Inline Dripper. These round disc emitters connect onto the supply line-no fittings needed. The inline dripper has an integrated barb inlet on each side that fits 1/4 in. tubing, and emits water from the colored side. Position a series of emitters along the tubing to supply water to each plant. Works best on level ground and short circuits to water individual plants, shrubs, and trees alongside your supply tubing. Periodically check for clogged emitters, which can choke off emitters downstream. Inline Drippers are made of polyethylene treated with UV inhibitors.
