Key features

• 15 Pack Thin-Wall 1/2 Inch Drip Line Coupler SetThis package comes with 15 pieces of barbed drip irrigation couplers exclusively designed for thin-wall 1/2-inch drip tubing. IMPORTANT: Only compatible with thin-wall drip tubes with 0.60–0.65" outer diameter; NOT fit thick-wall standard irrigation tubing over 0.65" OD. Please measure your tube outer diameter before purchase to avoid mismatching. These pipe connectors help you connect, extend and repair garden drip pipelines efficiently, ideal for daily irrigation maintenance of all small and medium planting scenes. Remember to fully tighten the green lock nuts after tubing insertion for complete leakproof performance.
• Precise Size Matching for Thin-Wall Drip TubingOur barbed couplers are customized for irrigation tubes with inner diameter 1/2 inch and outer diameter ranging from 0.60 to 0.65 inches. The built-in barb structure creates tight occlusion with thin-wall drip lines, delivering smooth water flow without seepage or detachment. Perfect for repairing broken tubes or expanding your existing micro drip irrigation setup. Double-check your pipe OD before ordering to confirm compatibility.
• Quick Tool-Free Installation with Anti-Leak DesignNo extra tools required for assembly. Each coupler features integrated barbs paired with twistable green lock nuts. Just slide lock nuts onto tubing, insert the pipe fully into the barbed port, then hand-tighten the nuts to lock the tube firmly in place. The matched internal rubber ring provides stable clamping force, preventing water leakage under normal irrigation working pressure. Avoid forcing thick oversized tubes into the fitting to prevent cracking.
• Heavy-Duty Anti-Aging Plastic ConstructionMade of premium rigid UV-resistant plastic, this one-piece barb and lock nut connector resists outdoor sunlight, aging, corrosion and moderate water pressure. It can withstand long-term exposure to harsh garden outdoor conditions without deformation or breakage, offering stable long-lasting service for your seasonal and year-round irrigation projects.
• Wide Usage for Custom Thin-Wall Drip Irrigation LayoutThese tubing couplers support customized micro-sprinkler and drip watering systems built with qualified 0.60–0.65" OD thin-wall 1/2 inch tubing. Widely applied in raised garden beds, small greenhouses, patios, residential lawns and light agricultural irrigation. Suitable for both amateur gardening beginners and professional growers, delivering reliable leak-free connection for all matching thin-wall drip pipe layouts.
