The 1/4" barbed connector is used to connect two ends of our 1/4" micro tubing. It will also work with tubing that has an ID (Inside Diameter) of .140 to .170.
The 1/4" barb connector is also used to extend the micro tubing from 1/2" or 3/4" drip tubing. Using a punch to make a hole in the larger tubing this fitting is inserted in the hole and the microtube is pushed over the other end of the barb.
