Unthread the female end and remove the inner collar. Leave the male end to the side for now.
Push the braided line through in the inside of the female end, threads facing out.Push the plastic tubing (inside the braided line) into the inside of the collar until it is almost flush.
Slide the female end over the collar. Thread male end and you're complete.
Clean fit.
Ready for the cooler. Which by the way I'm still looking for.
