Hey,
Flare nut wrenches are a very handy tool to have around. Also very expensive. For me anyway.
If your going to purchase a set I would recommend getting the best you can get. Like Snap-on, Sears would be ok I guess but not Ace hardware or Walmart. If they even sell them.

The reason is the cheaper brands aren't as sturdy and give a lot of play with the boxed end being open the way they are.

Just my 2c.

Danny
