The 1/4 in. Barb Coupling with Profile Disc connects two sections of 1/4 in. distribution tubing (A220 and A250) or 1/4 in. DuraFlo™ JR dripline. Coupler features a sturdy disc to support your finger, making it easier to hold and insert into tubing. The barb connector fits inside drip tubing and anchors into place. 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.
