This 1/4 in. drip irrigation tube has an inner diameter of 4mm, outer diameter of 7mm, and a 3mm thick wall, delivering double explosion-proof protection to stop accidental leaks or bursts from sudden pressure shifts during use. It includes a 6-way connector, 20 pieces of 1/4 in. tee splitters, and 20 pieces of 1/4 in. end plugs to support full irrigation setup. Made from polyethylene and a new odorless flexible fabric material, this hose is ROSH-certified, offering year-round durability across all weather conditions, withstanding temperatures between -20℃ and 70℃. It can serve as the main line for small drip irrigation systems, or branch off from larger 1/2 in. drip tubing to build out micro-watering setups. Its flexible construction lets it fit tightly into curved or switchback planting areas, and installation is simple: just cut the tube to your preferred length and connect it to barbed fittings, emitter streams, vortex emitters, or misting nozzles.
