Check the listing for details. Barbed Reducing Elbow 3/4" x 1/2" 10 pack. Condition: New, Made in United States. Listed at 31.95 USD. The Barbed Reducing Elbow is a specialized fitting designed to streamline your irrigation layout by performing two tasks at once: making a clean 90-degree turn and stepping down your mainline size. This fitting is most commonly used to transition from a larger 3/4" poly tubing header to a 1/2" zone line, eliminating the need for separate couplers or reducers. Constructed from durable gray PVC, these insert irrigation fittings feature sharp, high-grip barbs that "bite" into the interior wall of the tubing. This creates a tight, leak-resistant seal that holds firm even under the pressure fluctuations common in agricultural and residential drip systems. By combining the turn and the reduction into a single unit, you reduce the number of potential leak points in your garden.
