The 10-32 Threaded X 1/4 in. Barb Adapter makes the transition from a rigid riser to 1/4 in. distribution tubing (A220 and A250) or 1/4 in. DuraFlo™ JR dripline. This micro fitting is made of ABS plastic treated with UV inhibitors to prevent fading and cracking. Use fittings to set up a new drip irrigation system, expand an existing system, or make repairs.
