1/2 Inch Perma-Loc Coupling. Fits .6 inch inside diameter polyethylene tubing.
Do not require any glue or clamps to connect to hose. These fittings are the easiest to use- recommended if you have arthritis or less than macho strength in your hands. Also, these are easy to remove from hose for rearranging or reuse. Insert hose and spin fitting tight. Rovides very positive seal. The 600 series fits 18mm drip hose and 1/2" dripperline.

These are the best drip line couplings I have ever seen! The precisely made threads move smoothly and swiftly out, pressing the tubing tightly
against the tapered coupling shaft so that the water is contained within the line. The black color is uniform throughout the coupling, and the ribbed design of the outer surface is easily gripped and twisted. In addition, they are quite lightweight, so that even an elf or. a hobbit could carry two of them easily.

When out on the field when a long length of drip line is not needed time and cost is saved. It is a perfect fix with guarantee results.
