Apply and remove O-Clamps with this very popular clamp crimping tool. It has side pincers to get you an extra secure fit and it’s easy and comfortable to use. When you’re attaching O-clamps to your beer or air lines, this crimping tool gives you a tight seal with no gaps, that won’t loosen up over time. You can’t say that about traditional drive clamps! It’s also quite handy for cutting wire, strapping, pulling nails and more!
