Insert a 90 bend to your drip system with the 1/4 in. Barbed Elbow. This micro fitting connects two sections of 1/4 in. supply tubing or dripline, or connects 1/4 in. tubing to a punched hole on any size supply line. To install, insert the single-barbed tip inside the drip tubing opening and anchor in place. For rigid tubing, try soaking the tube in hot water or leaving out in the sun to make it more pliable. Use the fittings to set up a new drip system or expand or repair an existing system. Reusable micro fitting is made of acrylonitrile butadiene styrene (ABS).
