Not all hose barbs are created equal! This 2″ Tri-Clamp x barb fitting features a shorter profile and over sized diameter barb. The over sized barb (5/8″ OD) is specially designed for 1/2″ Silicone tubing. The larger size does two things: 1) It stretches the tubing over the barb creating a tight fit requiring no hose clamps. 2) The inside diameter of the barb is 1/2″ compared to standard 1/2″ barbs which have a smaller 3/8″ size. This creates a full port design and will not restrict flow going through the barb.
