The 1/4" barbed elbow is used to make sharp turns with 1/4" microtube. It can also be used to attach 1/4" microtube to 1/2" or 3/4" drip tubing. It will work with any of our 1/4" microtube or any 1/4" tubing that has an ID (Inside Diameter) of .140 to .170.
Use a punch to make a hole in the larger tubing and this fitting is inserted in the hole and the microtube is pushed over the other ends of the barbs.
